FIELD OF THE DISCLOSURE

The field of the disclosure is furniture, and more specifically, furniture having on-board power sufficient to enable use of one or more feature modules, on board sensor devices and, in at least some cases, on board or associated actuators that can be controlled to change various environmental characteristics associated with the furniture. This disclosure also describes a system for providing feedback and encouragement to furniture users to encourage healthy behaviors.

BACKGROUND OF THE DISCLOSURE

The value of electronic sensing devices for sensing physiological parameters of a person has been known in the medical industry for many years. To this end, many sensing devices have been developed that can be adhered or mechanically attached to a person's body at specific locations to sense specific parameter such as heart beat, breathing rate, temperature, blood flow, perspiration rate, etc. In addition, many applications have been developed to use sensed physiological parameters data to determine other conditions of a person. In some cases, physicians or other health care specialists have used sensed data to detect physical conditions of clients and to advise clients on lifestyle changes designed to help clients live healthier lives. In other cases, systems have been developed for home use to monitor biometric parameters and provide feedback to a person or the person's physician to indicate current health conditions or physiological parameter trending over time. In some cases sensed data has been used by other entities such as, for instance, insurance companies, to customize policies based on perceived health of particular persons.

One problem with early sensing systems was that those systems generally required a person to be located at a specific location in order to use the sensing systems. For instance, in some cases a person was required to be at a medical facility to be connected up to a sensing system. As another instance, in some cases a person was required to be at home where a processor and sensor assembly was located in order to use a sensing system.

Recently, with the advent of smaller electronic devices, smaller power sources and portable interface devices (e.g., smart phones, pad-type devices, etc.), many personal portable sensing devices have been developed along with associated applications that can be used by individuals or proxies (e.g., a primary care physician) to track physiological parameters over long periods of time outside of a hospital or home environment. For instance, there are many wrist mountable devices on the market today which monitor various physiological parameters and provide those parameters to an application run on a computing device (e.g., a pad-type device) which in turn processes the received data and outputs the data or other data derived therefrom to the person wearing the device for consideration. In many cases the idea here is to make a person aware of their physiological parameters and encourage a lifestyle change or at least maintenance of a healthy lifestyle that currently exists. Thereafter, the person receiving the data is required to act based on the received data to change or maintain their lifestyle. One particular advantage of wearable devices is that those devices may be in contact with a person's body for many hours each day and therefore data can be obtained over long periods of time and during different activities (e.g., exercise, relaxation, cognitively stressful periods, etc.). Thus, these devices that are in contact with a person's body over the long term, can feed new and more complex applications based on long term parameter values.

In addition to physiological parameter sensors, other sensor systems and devices have been developed for sensing various aspects of a person's behavior. For instance, wrist mounted or otherwise wearable pedometers have been developed that can estimate or count the number of steps a person takes during the course of a day or a distance traveled during a day or during an event (e.g., during a run). Other sensors have been developed to sense other behaviors or activities of a person (e.g., sitting, standing, etc.).

One problem with wearable devices like wrist mounted devices is that many people simply do not like wearing electronic devices. For instance, in many cases these devices are relatively large and clunky and can physically get in the way of some activities. As another instance, many wearable devices have an industrial look and feel and therefore are aesthetically unappealing. Still one other problem with wearable devices is that many of these devices are expensive and therefore cannot be personally purchased by many people that would like to take advantage of the functionality associated therewith. Still one other problem with these devices is that they typically require batteries and therefore, at least periodically, require some affirmative step by a user to initiate a recharge cycle. In most cases recharging require removal of the device and connection to some stationary charging station. Still one other problem with these devices is that they require a user to react correctly to generated data in order to make a change in the person's health (i.e., if a person is too sedentary, the person needs to become more active to improve their health).

One way to overcome many of the problems associated with wearable sensing devices is to provide sensing devices within a person's environment that are separate from the person but in proximity such that the devices can still sense physiological parameters and behaviors. Optimal places for sensors are locations where a person is located for a long time. For instance, most people spend one quarter to one third of their time in their beds. For this reason, some systems have been developed to place at least some types of sensors in mattress or other bed structure. As another instance, many people spend at least some time each day driving in their vehicles. For this reason, some systems have been developed that include sensors proximate a vehicle driver for sensing biometrics.

For many people, the place they spend most of their time after their bed is at work. For instance, many people spend eight, ten, or more hours at a facility operated by their employer. In many cases when a person spends a lot of time at work, most of that time is spent in a relatively small area. For example, many employees spend most of their time at work in a personal office or at a personal workstation or in a temporarily selected office or workstation. In fact, in many cases, a person spends most of her time in only a portion of an office or space proximate a work station. For instance, in many cases, an employee will be seated in a task chair proximate a desk or workstation where the chair is only moved within a small area (e.g., 5 by 5 feet) throughout a work day. In fact, in many cases a hard plastic floor mat is provided under a task chair to facilitate movement of the chair on casters adjacent a desk or workstation. Here, in most cases, a person is inclined to use their chair on the mat within the relatively small space (e.g., 5 by 5 feet) defined thereby. In cases where there is no mat, a person still typically only uses their chair in a space immediately adjacent a work station. Thus, in many cases each employee within an employer's facility spends most of her time within a relatively small defined space.

With respect to poor habits or behaviors or physiological parameters that adversely affect a person's health, it may be that some unhealthy activities for certain people occur at work. For instance, it is known that it is unhealthy for a person to remain stationary for long periods of time. Nevertheless, many people sit in a task chair for hours at a time without standing, walking or other physical activity. As another instance, it is known that it may be unhealthy to remain in the same position for a long time as such inaction puts undue stress on certain parts of a person's body which, in many cases, ultimately results in some form of pain. Nevertheless, many people working at a workstation maintain a single position, often times with poor posture, for hours on end without significant movement.

One other behavior that is often more prevalent within a working environment than in home environments is poor eating. In this regard, while people can control the foods they bring into their homes and often can spend additional time seeking out and preparing healthy foods when not at work, time restraints and lack of cooking resources often mean that eating habits at work facilities suffer appreciably. Poor eating habits are exacerbated in work environments where co-workers often bring unhealthy options to share during holidays or special occasions when there is added pressure to participate in festivities.

Thus, for various reasons it makes sense to provide physiological parameter sensors and behavioral sensors in work spaces used by people. First, many people are located in their work spaces for long and continuous periods and therefore instantaneous and long term physiological parameter data can be collected and analyzed. Second, by providing sensors to sense physiological and behavioral data within a work space, that data can be collected during normal daily activities to get a different view of a person's health and behavior. Third, by detecting parameters and behavior essentially in real time in a work environment, feedback can be provided to a person whenever some parameter is outside a range of acceptable values or when an altered behavior is determined to be relatively optimal.

A typical workstation includes, among other things, a desk or table that forms at least one work surface and a task chair adjacent thereto. In many cases a workstation will also include some type of stationary computing device such as a computer with a keyboard for user input and a flat panel or other type of display screen for providing information to a workstation user. A task chair is the one workstation device or assembly that most workstation users are in contact with most of the time while using a workstation. For this reason, locating sensors within a chair seat for sensing basic information such as presence, temperature, etc., is particularly advantageous and is generally known.

One problem with placing a sensor in a mobile chair has to do with how to get power to the sensors and how to get data from the sensors to a system processor for analysis, storage and reporting.

Thus, what is needed is a system that can sense many different physiological parameters of a person within a workspace and can use sensed parameter values to perform various functions. More specifically, what is needed is a system including sensors provided within furniture affordances that are proximate a workspace user and that optimally make contact (either direct or through clothing) with a person during workspace use so that reliable physiological parameter data can be obtained. In the case of a task chair, what is needed is a way to deliver power to the chair for powering sensors that is efficient and extremely easy to use, optimally requiring little if any activity from a chair user to provide the power. In addition, it would be advantageous if a chair could automatically adjust operations as a function of sensed physiological parameters or behaviors of a user of the chair in ways intended to increase overall chair user health and wellbeing.

SUMMARY OF THE DISCLOSURE

It has been recognized that, other than a bed, office furniture are objects that many people make contact with during the course of a day. For this reason, placement of physiological sensors in office furniture such as an office chair is particularly advantageous. The value of placement of sensors within a chair that a person contacts for hours a day is enhanced as often times health challenges may occur during working hours when a person is too sedentary, sometimes under stress and often times eating foods that are less than optimal.

It has also been recognized that the locations of sensors on or in a chair can appreciably affect the accuracy of the data obtained thereby. For instance, placement of a sensor on a chair arm rest where a bare forearm may reside or where a forearm is often covered with a relatively thin shirt material may be advantageous. Similarly, placement of a sensor in the front surface of a backrest may also be advantageous. Seat sensors may also be advantageous, for example, placement of a sensor in the front edge of a seat may yield accurate data when the back portion of a user's knees are pressed up against the front edge of the seat.

It has further been recognized that where a moveable/portable chair includes an on-board battery, a charging system may be provided that automatically starts charging when no person is located within a pre-defined space and where charging is discontinued automatically whenever someone enters the predefined space. For instance, in at least some embodiments a 5 by 5 foot chair mat may be fitted with one or more inductive coupling antennas and a coil may be mounted to the underside of the chair (e.g., within the base of the chair). A sensor may sense when no one is in a room in which the chair is located and may start battery charging when no one is in the room. Upon sensing a person entering the space, the system may automatically stop charging the battery. Thus, for instance, if a person leaves a room to grab lunch, while the person is outside the room, the system may charge the battery through the mat. By charging the battery only when no one is in the room, any concerns a person may have about being present within an inductive field are avoided. As another instance, when no person is located proximate the charging mat (e.g., a specific space), the system may start the charging process.

In other cases, instead of including an inductive mat with a chair that includes a coil, an electrical mat may be provided for use with a chair that includes electrical probes or brushes that extend down from an undersurface of the chair to the mat to make electrical contact therewith for battery charging purposes. Here, again, charging may only occur when there is no one in a space (e.g., a room, a proximate area about the mat, etc.). In some cases the probes or brushes may be stationary and always contact the charging matt there below. In other cases, the probes may be mounted to pistons or the like that are powered to move the probes up and down to break and make contact with the charging pad there below. Here, for instance, where a chair has a five spoke base with wheels or casters at distal ends, first and second probes may be mounted to two of the spokes proximate two of the casters. When a person is in a room in which the chair is located, the probes may be raised up so that they do not contact the mat and power to the mat may be turned off. When no person is located in the room, the probes may be pushed downward and contact the mat to start the charging process.

Moveable electrical probes may be provided on other parts of a task chair for connection to other charging devices. For instance, in some cases first and second probes may be provided in the top surfaces of first and second chair armrest members. Here, a charging mat or similar device may be provided on the undersurface of a workstation table. To charge a battery mounted on the chair, the chair may have to be placed in a stowed position with the armrests under a front edge of the workstation table below the charging mat. When so positioned, the system may cause the armrests to raise so that the probes contact the charging mat and charging commences. In other cases the probes themselves instead of the armrests may be raised to make contact with the charging mat. In this case, instead of sensing the location of a person, the system may sense the location of the chair relative to the charging mat. Here, charging would not occur until the chair is in a location under the workstation, which would prevent a person from sitting on the chair. In other cases charging still may not occur until no one is sensed within the room or the space associated with the chair.

In at least some cases, instead of providing a motorized moveable probe on the chair, the moveable probes may be provided as part of the charging mat or device. For instance, in the case of a mat on the undersurface of a workstation table, a motor may drive the mat downward when chair arms are located beneath the workstation so that different parts (e.g., positive and negative) of the mat contact the armrest members for charging purposes. By providing the motors and moveable probes on the workstation as opposed to the moveable chair several advantages result. First, the chair can have an appearance that is more like the appearance of popular task chairs manufactured today. Second, motors and moveable probes that may be relatively more subject to damage than other components are provided as part of a stationary furniture affordance as opposed to the moveable chair which should result in a more robust overall design.

The sensor that determines if a person is within the space and/or the location of a chair within a space may take any of several different forms including a simple presence sensor, an entry and exit counter, a movement sensor, a camera that processes high definition images, etc.

In at least some embodiments it is contemplated that some type of indicator may be provided that affirmatively indicates whether a chair battery is being charged. For example, there may be an indicator that signals to a user of a chair that the chair battery is not being charged while the chair is in use. Where an indicator of no charge is provided, any user concern regarding simultaneous charging may be eliminated. For example, in some cases a small device may be provided for placement on the top surface of a workstation table or the like that includes red and green LED indicators aligned with a two state legend that indicates “charging” and “not charging”, respectively. Here, when the green LED is illuminated, a chair user would know that the battery is not being charged and when the red LED is illuminated a person could determine that the chair is currently being charged.

In any case where a chair needs to be positioned relative to a charging device for a battery to be charged, it is contemplated that one or more motors may be provided on the chair for moving the chair to a charging position automatically. For instance, where a chair seat is mounted for rotation about a center post to a castered base, one motor may be provided on one of the casters and a second motor may be provided on the base to rotate the seat there above to any rotational angle with respect to the base. The motor on the caster should be able to move the base to any location on a floor mat or an ambient floor there below, albeit where the base may assume any orientation. The second motor between the base and the seat should be controllable to rotate the seat to a position where the armrests are directed toward an open space under the workstation table top and a charging pad mounted there under, once the seat and armrest are aligned with the open space, the first caster motor can drive the chair toward the table until the arm rests are located under the pad. While the chair is moving toward the table, if the base rotates somewhat, the motor between the base and the seat can compensate for that rotation by rotating the seat and armrests attached thereto to maintain alignment with the pad. Once the armrests are under the pad, the pad may be lowered to contact probes in the armrests and charge the batter. In an alternative embodiment the two motors may be linked to first and second different casters for driving the chair into the charging position.

Where a chair base includes five casters, the first and second powered casters may be adjacent each other or may be separated by a non-powered caster. In either case, the two powered casters may be controlled together to move the chair to any desired position for charging.

In at least some cases where a chair includes motors, when a person enters a space associated with the chair during a charging cycle, in addition to automatically stopping the charging cycle, the system may also control the motors in the chair to move the chair into a welcoming position facing an entry egress into the space. For instance, a motor may drive a powered caster to move the chair back away from a charging position proximate a workstation table and a motor between the chair base and the seat may rotate the seat to face the egress. In some cases, after a chair battery is fully charged, the chair motors may be controlled to automatically move the chair into the welcoming position regardless of whether or not a person is located within the space associated with the chair.

In some cases, instead of powering one or more casters for moving a chair to a charging position, a separate driving device may be provided that is designed specifically to move the chair toward and/or away from a charging position. To this end, for instance, a driving device including first and second spaced apart wheels may be provided below a central portion of a chair base. Here, the driving member may be at least couplable to a central pivot post between the base and a seat and the two wheels that comprise part of the driving device may be located on opposite sides of a vertical axis through the central pivot post. In this case, where the wheels are driven in opposite directions while the driving member is coupled to the central post, the seat may be rotated and where the wheels are driven in the same direction the chair may be moved from one location to another. Thus, both rotational and directional control using a single driving device may be facilitated.

It has also been recognized that a chair can be used automatically to change a condition or a person's behavior when some undesirable condition occurs. For instance, in at least some embodiments, motors may be provided on a chair and linked to various components to alter the relative juxtaposition of chair components periodically to change the position of a person sitting in the chair.

For instance, a user may be an employee of a company or other entity (i.e., an enterprise) that uses a task chair and a workstation (e.g., resources) in a company facility.

Reference numeral 10 (FIGS. 1-6) generally designates a chair assembly as set forth in the present disclosure. In the illustrated example, the chair assembly 10 includes a base assembly 12, a support assembly 14 affixed to the base assembly 12, a seat assembly 16 affixed to the support assembly, a back assembly 18 affixed to the seat assembly 16 or the support assembly 14, and a pair of arm assemblies 20 each affixed to the seat assembly 16, the back assembly 18, or the support assembly 14. FIG. 1 shows the chair assembly 10 in a perspective view from the front-left of the chair assembly 10. FIG. 2 shows the chair assembly from the front of the chair assembly 10. FIG. 3 shows the chair assembly from the top of the chair assembly 10. FIG. 4 shows the chair assembly from the bottom of the chair assembly. FIG. 5 shows the chair assembly from the left side of the chair assembly 10. FIG. 6 shows the chair assembly from the back of the chair assembly 10.

While this disclosure focuses on aspects relating to a chair assembly 10, it is contemplated that many of the features described herein can be deployed in other types of furniture, such as the following non-limiting examples: a couch, a bed, a table, a cart, a monitor assembly, a projection screen assembly, and the like.

The base assembly 12 can take the form shown in FIGS. 1-6 or any other form known to be suitable for stably supporting the rest of the chair assembly 10 while a user occupies the chair assembly 10. The exemplary base assembly 12 includes an integral base member 13 and five casters 15. The base member 13 is a five spoke base member that may be formed of metal, plastic or any other rigid material. A separate caster 15 is mounted to a distal end of each of the five base spokes. Each caster can swivel about a vertical axis as well as rotate about a horizontal axis.

Examples of other suitable base assemblies 12 include, but are not limited to, at least three radially-oriented arms having rolling members affixed thereto for engaging a surface, a single base member having a footprint that is sufficient for supporting the chair assembly 10 and having a plurality of rolling members affixed thereto for engaging a surface, an assembly with one or more rolling members for engaging a surface and a gyroscopic device for maintaining balance of the chair assembly, and the like.

The support assembly 14 can take the form shown in FIGS. 1-6 or any other form known to be suitable for stably connecting the base assembly 12 with the remainder of the chair assembly 10. The exemplary support assembly 14 includes a post member 17 and an upper support assembly 19. Post 17 extends upward from a central portion of the base member 13 and upper support assembly 19 is mounted to the top end of the post 17 for rotation about a vertical axis. In at least some embodiments post 17 may be mounted to the base member 13 so that the post can be raised and lowered to accommodate different seat height preferences by a chair user.

While not shown in detail, support assembly 19 may have many different features and subassemblies that facilitate various adjustments of chair components to accommodate different user preferences. For instance, assembly 19 may include subassemblies that allow seat 16 to be moved forward and rearward relative to post 17 or may allow the front or rear portion of the seat 19 to be raised and lowered to accommodate different preferred seat tilt angles. As another instance, assembly 19 may include a sub-assembly that enables adjustment of the force required to tilt seat 16. In some embodiments, the base assembly 12 and the support assembly 14 may be integrated into a combined base/support assembly.

The seat assembly 16 can take the form shown in FIGS. 1-6 or any other form known to be suitable for supporting the weight of a user substantially from below the user. The seat assembly 16 can be configured to ergonomically support a user's buttocks, thighs, knees, shins, ankles, or any combinations thereof. The exemplary seat assembly 16 includes, among other features, a top surface 21 having a front edge portion 23, a rear portion 45, and first and second lateral portions 41 and 43, respectively. In at least some embodiments the seat assembly 16 may include a plastic or other type rigid shell member, a foam cushion mounted to or over molded onto the shell member and a fabric, leather or other material cover member. In other embodiments the seat may include a stretched membrane fitted onto a circumferential frame. In still other embodiments the seat assembly 16 may simply included a molded plastic shell that forms a shape that compliments a user's buttocks.

The back assembly 18 can take the form shown in FIGS. 1-6 or any other form known to be suitable for supporting the weight of a user substantially from any side of the user, such as substantially from the back of the user. The back assembly 18 can be configured to ergonomically support a user's torso, head, arm, pelvis, thighs, or any combination thereof. The back assembly 18 is an optional feature and this disclosure envisions chair assemblies 10 that include no back assemblies 18.

The exemplary back assembly 18 includes, among other features, a front surface 35 that includes a central portion 27, first and second lateral portions 29 and 31 on opposite sides of the central portion and upper and lower portions 141 and 37 above and below the central portion. In at least some embodiments the back assembly 18 may include a plastic or other type rigid shell member, a foam cushion mounted to or over molded onto the shell member and a fabric, leather or other material cover member. In other embodiments the backrest assembly may include a stretched membrane fitted onto a circumferential frame. In still other embodiments the backrest assembly 18 may simply included a molded plastic shell that forms a shape that compliments a user's buttocks. In at least some embodiments the backrest assembly may also include other assemblies that allow a chair user to adjust various aspects of the backrest assembly to accommodate user preferences. For instance, in at least some cases one or more of the subassemblies may allow a user to adjust the lumbar support of the backrest assembly to raise/lower a lumbar support, to increase or decrease the lumbar support, to change the tilt of the front surface 35 of the backrest, to adjust the force required to recline the backrest, etc. Subassemblies for accomplishing these adjustments are well known in the art and therefore will not be described here in detail.

The arm assembly 20 can take the form shown in FIGS. 1-6 or any other form known to be suitable for supporting a user's arm substantially from the bottom or side of the user's arm. The arm assembly 20 can be configured to ergonomically support a user's upper arm, elbow, forearm, wrist, hand, or any combination thereof. The arm assembly 20 is an optional feature and this disclosure envisions chair assemblies 10 that include no arm assemblies 20.

The exemplary arm assembly 20 shown in FIG. 1 includes an arm support structure 51 and a forearm rest member 53 having a top surface 55 that can also be referred to as a comfort surface. Support structure 51 extends upward from upper support assembly 19 and generally angles upward and forward to an upper distal end. Forearm rest member 53 is mounted to the top distal end of support structure 51. Structure 51 includes components that can be adjusted to move the forearm support member 53 to any of several different positions. For instance, support member 53 may be moved upward or downward, forward or backward, inward (e.g., over the seat 16) or outward, may pivot about a vertical axis, etc., within supported ranges.

Chair assembly 10 is manually moveable across a smooth, flat floor surface by applying a lateral force.

Referring now to FIG. 7, in addition to the components described above, at least some embodiments of chair assembly 10 also include a processor 58, a power supply 22, and one or more of a sensing module or sensor 61, 63, 65 and/or one or more application modules or actuators 73, 75 and 77. Hereinafter, the phrase “feature module” will be used to refer to either of a sensor or an application module.

Processor 58 includes circuitry for performing various functions required to support whatever features chair 10 includes. For instance, processor 58 may include a memory device that stores software that can be used to perform various functions such as obtaining sensed data from a sensor, processing the obtained data and generating some type of output. For instance, the output may include transmission of the data or some conclusion derived there from to server or the like via an access point within the vicinity of chair 10. As another instance, processor 58 may be programmed to control one or more motors (e.g., an application module) to change the relative juxtapositions of chair 10 components either under control from a chair user or automatically based on some sensed circumstance. It is contemplated that processor 58 may be programmed to perform many other processes, some of which are described hereinafter.

In addition to including circuitry and a memory for storing programs, processor 58 may include a memory for storing at least some sensed data from one or more sensors included in the chair 10.

Power supply 22 may be any type of power supply in at least some embodiments. For instance, supply 22 may include a transformer linked to a cord that can be plugged into a powered receptacle to power processor 58, sensors and other modules. As another instance, supply 22 may include a battery that can be periodically replaced. As yet another instance, supply 22 may include a rechargeable battery pack that can be removed and replaced, where the removed battery pack can be recharged as the replacement battery pack is being used. In still other embodiments, supply 22 may include a rechargeable battery that can be recharged periodically. Where supply 22 is rechargeable or needs to be connected to a receptacle, a power connector 60 is provided that is linked to supply 22.

Referring again to FIG. 1, rechargeable power supply 22 is shown mounted at various positions on chair assembly 10. For example, the rechargeable power supply 22 can be located in or affixed to the base assembly 12, the support assembly 14, the seat assembly 16, the back assembly 18, the arm assembly 20, or any combination thereof. It should be appreciated that the rechargeable power supply 22 can occupy any location within the chair assembly 10, so long as the rechargeable power supply 22 can be sufficiently supported by the chair assembly 10 and can be operably coupled to aspects of the chair assembly 10 that relate to charging and usage of power. Supply 22 can include two or more power supply units, which can be located adjacent to one another or remote from one another. Supply 22 can be configured to transmit a power level signal to the processor, which indicates the power level of the rechargeable power supply.

Sensors 61, 63, 65, etc., may take any of several different forms and at least some exemplary sensor types are described hereinafter. In general, a sensor may be for sensing any of several different types of parameters including user input parameters (e.g., parameters input by a chair user to adjust the chair or to indicate a user's condition), biometric or physiological parameters (e.g., temperature, heart rate, blood flow, respiratory rate, etc.), behavioral parameters (e.g., a chair user's position, rate of movement, etc.), chair arrangement parameters (e.g., tilt of backrest, height of seat, position of forearm support member, etc.) or chair juxtaposition parameters (e.g., location of chair 10 within an ambient space or relative to some affordance (e.g., a charging station) within the ambient space).

Application modules 73, 75, 77 include subassemblies or systems that perform some activity such as chair component adjustment, heating or cooling adjustment, control of haptic activities, providing feedback to a chair user, automatic movement of the chair to different locations within an ambient space (e.g., for alignment with a recharging station), automatic adjustment of chair orientation, controlling hardware required for recharging in some cases, etc.

Processor 58 can be located in or affixed to base assembly 12, support assembly 14, seat assembly 16, backrest assembly 18, or an arm assembly 20. The chair-assembly-based processor can occupy substantially the same locations as the feature modules (e.g., sensors and application modules) described below in at least some embodiments.

In at least some embodiments at least some of the processes and methods described herein may be performed by one or more processors that reside external to chair 10 or by the chair processor in conjunction with one of the external processors. For example, see user-based processor 52 and facility-based processor 54 in FIG. 7. User-based processor 52 includes a processor that is located on, within, or near (e.g., carried by) a user. For example, a person using chair 10 may also use a portable computing device like a smart phone, a pad type computing device, a laptop computer, a wrist or otherwise wearable computing device such as smart jewelry, smart clothing, smart footwear, smart handwear, smart eyewear, ear technology with an on-board processor, such as a hearing aid or smart contact lenses; or in an implantable device, such as an implantable computing device. Here, processor 52 may receive signals from the chair based processor 58 via a wireless transceiver 67 (e.g., transmitted-receiver) in chair 10 and a mobile device transceiver 87. Thus, in some cases, processor 58 may obtain sensed data from sensors 61, 63, etc., and provide the raw data to processor 52 which would process the information and determine what to do with the results. In some cases the results may cause processor 52 to transmit control signals back to chair 58 to perform some function.

Referring still to FIG. 7, facility based processor 54 includes one or more processors that are associated with the facility in which chair resides and may include, for instance, a processor that forms part of a facility server, a desktop or other stationary computer within the room in which chair 10 is located, etc. In some cases processor 54 may be remotely located in a different facility (e.g., an enterprise server in a headquarters building in a remote city). Processor 54 may be linked to one or more access points 69 in a facility for wirelessly communicating with transceiver 67.

In some cases there may be sensors and application modules that are located outside chair 10 and that are linked or at least linkable to one of the user-based processor 52 or the facility-based processor 54. To this end, see again FIG. 7 that shows portable device sensors 89 and application modules 91 linked to processor 52 and sensors 93 and application modules 95 linked to the facility-based processor 54. Here, for instance, a biometric sensor located in a wrist mounted computer may sense one or more physiological parameters of a wearer and may transmit that data to chair processor 58 to be processed. In the alternative, the wrist based processor 52 may process the physiological parameter and transmit a control signal based thereon to the chair processor 58 to perform some function. As another instance, where a smart phone includes processor 52, data sensed by chair processor 67 may be used to drive a vibrator or the like (e.g., an application module 91) in the phone to provide some signal to a chair user (e.g., to signal that the user should change position if the user has been too stagnant in one application).

Similarly, facility-base processor 54 may receive signals from sensors 93 or from processor 58 and perform various functions to control application modules 95 or to send command signals back to processor 58 to perform some function to control one or more application modules 73, 75, 77, etc. For instance, one of sensors 93 may include a camera (see 100 or 102 in FIG. 8 or 516 in FIG. 31) that senses when no one is in a space associated with chair 10. When no one is in the space associated with chair 10, processor 54 may perform some function to start a battery recharging process. As another instance, when any of the system processors recognizes, based on sensed data, that a person sitting in chair 10 is becoming drowsy, facility-based processor 54 may control lighting in the space that includes chair 10 to increase intensity to help the person wake up. Many other processes associated with application modules are contemplated, many of which are described hereafter.

The chair-assembly-based processor 58, the user-based processor 52, and the facility-based processor 54 can communicate signals to one another to achieve any of the various sensing, application, operations, or functions described herein.

In at least some embodiments chair assembly 10 may contain one or more features that are inactive until activated by an application run on a device containing a user-based processor. For example, chair assembly 10 may contain a heating function or other function that is inactive until a user activates the heating function or other function from an application run on the portable device that includes processor 52.

Chair Assembly Power

In at least some embodiments the amount of power required to operate chair components may be relatively small. For instance, where a chair 10 only includes one or a small number of sensing devices and a transceiver to transmit sensed data to an off-chair processor and no actuators (e.g., application modules), the power required by the chair features may be relatively small. In other cases the amount of power required to support chair features may be relatively large. For instance, where a chair 10 includes a large number of sensors and/or one or more actuators such as motors, vibrators, heaters, cooling mechanisms, etc. the required power may be substantial. The type of power source 22 selected for a chair will be related to the amount of power required by the chair. For instance, where minimal power is required, a relatively small solar cell may be provided on a chair surface that can collect energy from an ambient light source to drive components. To this end, see exemplary solar cell 200 shown on a rear surface of the backrest assembly 18 in FIG. 6. Cell 200 may provide power directly to feature modules or may be linked to a rechargeable battery type power source 22 to store power which is then fed to processor 58, features modules and other devices (e.g., the transceiver 67) when required.

Where a more substantial amount of power is required, several power options are available, some of which are more advantageous than others. For instance, see exemplary power cord assembly 202 in FIG. 5. Assembly 202 includes a spring loaded retractor mechanism 204 and a cord 206. Cord 206 has a proximal end 208 linked to chair support assembly 14 and a distal end 210 where an intermediate portion between ends 208 and 210 passes through retractor mechanism 204 to be wound thereby. Here, distal end 210 can be pulled from mechanism 204 and plugged into a powered receptacle (not illustrated), for example in a wall or in another device. In this case, power source 22 may include a power transformer and cord 206 may have to be plugged into a receptacle at any time that power is required by chair components. When power is not required, mechanism 204 may be used to aid in winding cord 206 into a housing structure for storage.

In other embodiments power source 22 may include a battery or some other type of replaceable fuel cell. Here, one advantage is that chair 10 can be used without requiring a cord 206 which often times can get in the way of a chair user. For instance, in many cases a chair user will rotate seat 16 several times during a day during normal use which can cause cord 206 to wrap around the chair base. One problem with batteries or other power sources that need to be periodically replaced is that they place a maintenance burden on a chair user or some other personnel.

In particularly advantageous embodiments it is contemplated that rechargeable batteries or fuel cells may be provided as power source 22. Examples of rechargeable batteries include, but are not limited to, a lithium-ion battery, a lithium-ion polymer battery, a nickel-cadmium battery, a nickel-metal hydride battery, a sealed lead acid battery, an alkaline battery, a nickel-hydrogen battery, a nickel-zinc battery, a lithium-air battery, a lithium cobalt oxide battery, a lithium sulfur battery, a lithium-titanate battery, a sodium-ion battery, a potassium-ion battery, a zinc bromide battery, a zinc cerium battery, a vanadium redox battery, a quantum battery, combinations thereof, and the like. The rechargeable battery can be in the form of a thin film battery, a smart battery, a nanowire battery, etc.

The present disclosure contemplates several different ways to recharge a battery, some requiring at least some manual steps by a chair user and others that are fully automated. For instance, referring again to FIG. 5, in a simple recharging case, the proximal end 208 of power cord 206 may be linked to a rechargeable battery 22. Here, when a chair user knows that she will be leaving her office for an extended period of time, she can simply pull distal cord end 210 from the retractor mechanism housing and plug the cord into a power receptacle. When the user returns, the user can unplug the cord and restore the cord in the storage housing to avoid entangling cord 206 with the chair base.

In other cases recharging power may be delivered to rechargeable battery 22 in ways that do not require a cord yet still require some simple user activity. For example, referring again to FIG. 7, in at least some cases it is contemplated that power connectors 66 may be built into the chair 10 for making a direct connection to recharging electrodes provided in some type of recharging subassembly that is separate from the chair 10. In this regard, see FIG. 8 that shows a chair assembly 10 in a private office 30 on a chair mat 28 adjacent a workstation table or desk 32. Here, a recharging station assembly 210 is provided that abuts an office wall adjacent an edge of mat 28. Referring also to FIG. 10, station assembly 210 has a low profile so that it lies low along a portion of the wall adjacent a floor surface and has a length dimension that is longer than a dimension defined by the distal ends of two of the chair base assembly spoke members 212 and 214. Referring also to FIG. 9, station assembly 210 includes a plate member 218 and a housing structure 220 that extend upward therefrom to form a sideways opening channel or cavity 222 that opens away from an adjacent office wall member and toward the mat 28 edge. Here, the channel 222 is designed to have an upper arm section which resides generally above a distal end of the spoke members 212 and 214 when those distal ends are places within the channel 222. Positive and negative electrodes 224 and 226 (shown in phantom in FIG. 10) are located on an undersurface of the upper arm section at spaced apart locations (e.g., at opposite ends of the length dimension of station 210). Lateral walls 228 and 230 (shown in phantom in FIG. 10) are provided at opposite ends of station 210 which limit the position in which the distal ends of spokes 212 and 214 can be placed and still be located within the channel 222.

Referring still to FIGS. 9 and 10, electrode pads 232 and 234 (see phantom in FIG. 10) are provided on the top surface portions of spokes 212 and 214 at their distal ends. As shown in FIG. 9, top surfaces of spokes 212 and 214 angle slightly downward when approaching the distal ends so that the pads 232 and 234 have a slight downward tilt.

Referring still to FIGS. 8 through 10, to place chair 10 in a charging position, a user aligns the distal ends of spokes 212 and 214 with channel 222 and moves the chair 10 toward station 210 until electrode pads 232 and 234 contact electrodes 24 and 226. Once the electrode pads contact the electrodes, charging can commence.

Referring again to FIG. 10, wall members 228 and 230 can restrict the position in which the distal spoke ends are located and electrodes 224 and 226 may be designed so that when the spoke ends are received in channel 222, the pads 232 and 234 will always make connection with electrodes 224 and 226. In at least some cases internal surfaces of the wall members 228 and 230 may angle toward each other when moving into channel 222 to help a user guide the spokes into the channel 222. Thus, a user need not hunt for where to place the spoke ends to link to the electrodes in the channel 222.

While only two spokes are shown in FIG. 10 as including electrode pads 232 and 234, in at least some embodiments it is contemplates that an electrode pad may be provided on the top surface of each of the five base spokes proximate distal ends. Here, a user could simply place any two spokes within channel 222 to start charging. In this case, chair processor 58 would be programmed to recognize which two spokes are in the channel 222 and would use those two spokes for charging purposes. Here, a mechanism in either chair 10 or in the charging station 210 would be programmed to make a polarity switch so that positive and negative pads and electrodes are properly aligned. For instance, in FIG. 10, electrode pad 232 may be positive or negative and pad 234 may be positive or negative, based on which charging electrode 224 or 26 the pad is aligned with.

In at least some embodiments it is contemplated that charging will start automatically once the electrode pads make contact with the electrodes 224 and 226 and that charging will continue until battery 22 is fully charged or a user pulls the chair back from station 210 for use. In some cases there will be a mechanism for cutting off power to electrodes 224 and 226 when chair 10 is not in the charging position. For instance, a system processor may monitor for chair position via electrodes 224 and 226 or via some other sensors and may cut power when the chair is not in the proper charging position. Similarly, it is contemplated that a mechanism within the chair will effectively disconnect pads 232 and 234 from the power source 22 until chair 10 is properly placed in a charging position at station 210. For instance, a switch may be provided within the chair assembly 10 that is controlled by chair processor 58 to open until the recharging position occurs. Here, once a system processor recognizes that pads 232 and 234 make contact with electrodes 224 and 226, the system server may send a signal to processor 58 to close the switch and commence the charging process.

In at least some embodiments a charging indicator of some type may be provided. For instance, see again FIG. 9 where an indicator 261 includes a red LED 263 and a green LED 265 mounted to an upper portion of structure 220. Here, when charging is not occurring, red LED 263 may be illuminated and when charging is taking place, green LED 265 may be illuminated.

One advantage to the recharging station 210 described above is that the form of the chair assembly 10 can be substantially similar to conventional chair assemblies and need not include moveable components specially designed to facilitate the charging process. Thus, pads 232 and 234 can be robust and rigid with respect to their supporting structures. The tilted angles of the spokes 212 and 214 facilitate connection to electrodes via a sort of wedging action.

In at least some embodiments it is contemplated that a charging station may include additional features to help ensure a good electrical contact between electrodes and pads. For example, see again FIG. 9 where a spring 250 is shown schematically linked to electrode 224 which may apply a slight downward force to electrode 224 to help maintain contact with pad 232. As another example, in FIGS. 9 and 10, a rib 252 extends up from a top surface of plate member 218 adjacent a front edge of the plate 218 which is positioned to bear against an edge of the casters 15 when distal ends of spokes 212 and 214 are places within channel 222 to hold pads 232 and 234 against electrodes 224 and 226 until the chair is affirmatively removed from the charging station 210.

Referring yet again to FIG. 9, in some embodiments a magnet 238 may be provided in channel 222 to face some surface of the spokes 212 and 214 at their distal ends and each spoke may have a metallic plate 230 at its distal end that is adjacent the magnet 238 upon insertion of the spokes 212 and 214 into channel 222 so that the magnet 238 can releasably hold the spokes in the charging position.

Other types of direct electrode charging stations are contemplated. For instance, see FIGS. 11 and 12 where a table top member 270 is shown along with a portion of a chair assembly 10. Here, spring loaded electrode pads 272 and 274 are located on an undersurface 275 of the top member 270 at spaced apart locations generally proximate a front edge of member 270. Referring also to FIG. 3, electrode pads 280 are provided on top surfaces of arm rest members 53. In this case, to charge a chair battery, a user would first adjust chair arm members to a highest position via the arm assemblies and perhaps by raising the chair support structure 14 (see again FIG. 1) and would then push the chair into a location with the arm members below electrodes 272 and 274. Again, some table structure (e.g., legs or other guide members) may be provided to help the user align the arm members and associated electrode pads with the spring loaded electrodes.

In at least some cases the spring loaded electrodes would be spaced rearward from the front edge of member 270 so that when the support members 53 are aligned under the spring loaded electrodes, the front surface of the backrest member 18 is immediately adjacent the front edge of the table top member 270 so that no user could be located within chair 10. Thus, once members 53 are aligned with electrode pads 272 and 274, charging could commence.

The spring loaded pads 272 and 274 would be located at a height below the top surfaces of members 53 and, in an least some embodiments, would be angled to face the direction in which members 53 move when chair 10 is moved toward the front edge of member 270 so that the contact surfaces would contact members 53 and raise against the spring force to accommodate members 53 there under. The pads 272 and 274 may have a convex external shape so that they can make better point contact with pads 280 in the arm members 53.

In still other embodiments charging electrodes or pads may be provided on one or more surfaces of other affordances within a space that includes a chair 10 where some portion of the chair may be moved into contact with the electrodes or pads to form a connection suitable for charging purposes. For example, electrodes may be provided on an upper rear edge portion of the backrest member 18 as at 290 in FIG. 5 for connection to a wall mounted charging station 300 (see again FIG. 8). In this case, the wall mounted charging station 300 may include vertically elongated and spaced apart first and second electrodes 302 and 304 so that the chair electrode pads at 290 are aligned with the pads 302 and 304 regardless of the height of the chair backrest 18 when the chair is moved into a charging position. Here again, some mechanism to hold the chair in the charging position may be provided such as a releasable magnetic locking subassembly (see again 260 in FIG. 9) a rib in a mat to capture an edge of the casters 15, a spring loaded mechanism to capture a rear frame section of the backrest assembly 18, etc.

Desirable features in the embodiments described above with respect to FIGS. 8 through 13 are a charging station that includes electrodes that are positioned and dimensioned to make contact with chair based electrodes or pads upon movement of the chair 10 in to a charging position, some type of guidance mechanism to help a user move the chair into a charging position where chair electrodes and charging electrodes are aligned and make contact and some type of retaining mechanism that retains the chair in the charging position until purposefully removed by the chair user. In each case described above, a charging indicator akin to the indicator 261 described above with respect to FIG. 9 may be provided at a location that is within the field of view 518 of a chair user.

In still other embodiments, it is contemplated that when a chair 10 is moved to a charging position with electrode pads adjacent charging electrodes, there may some mechanism for automatically moving the charging electrodes toward the chair mounted pads. To this end, see FIG. 13 where a motor is provided at 310 instead of the spring loading mechanism shown in FIG. 12. Here, the motor 310 may be controlled to move charging pads 272 and 274 up and down to engage the arm rest electrode pads 280 in the chair assembly 10. In this case, the chair user may not be required to move members 53 into a highest position to engage the charging electrodes 272 and 274. Instead, when the chair 10 is placed under the table top member 270, a sensor 312 (e.g., a proximity sensor, a camera within the office occupied by the chair, etc.) may sense the location of the chair and cause a system processor to control the motor 310 to move the pads 272 and 274 down into engagement with the electrode pads 280.

In at least some embodiments it is contemplated that at least one of a charging station and a chair assembly 10 may be equipped with a motive mechanism for moving the assembly to join the charging station and the chair assembly 10. For instance, referring again to FIG. 1, in at least some embodiments, first and second motors 320 and 322 may be provided as part of adjacent casters 15 for moving a chair assembly 10 about within an office space. In FIG. 1 the motors are shown extending from the casters for illustration purposes only and in an actual configuration the motors may be wholly located within a caster structure. Here, the motors would be for moving the chair when there is no one in the chair and therefore the motors would not have to be extremely powerful.

By controlling the motors 320 and 322, the chair processor 58 (see again FIG. 7) could move the chair assembly 10 and reorient the base 12 to any orientation within a room and therefore to align the base spokes (see 212 and 214 in FIG. 10) with a charging station 210. Thus, for instance, by maintaining one of the motorized casters in a stationary position and rotating the other motorized caster, the base could be turned in a controlled fashion. By powering each of the motorized casters in the same direction the chair could be moved along a relatively straight trajectory within a space. In at least some embodiments where a chair includes motorized casters on two base spokes, Electrode pads (e.g., 232 in FIG. 9) may only be provided on two of the spokes as opposed to all five and the chair processor 58 would be programmed to move the chair around until the two pads 232 and 234 make contact with charging station electrodes.

In other embodiments it may be advantageous to provide the first and second motorized casters on base spokes that are separated by a spoke that includes a non-motorized caster. In still other cases a single motorized caster may be able to operate to move a chair 10 into a charging position. Referring still to FIG. 1, in yet other embodiments a single post 350 may extend down from a central portion of the base member 12 and a dual action caster 352 may be provided on the lower end of the post 350 with a single motor 354 linked to the dual action caster 352. Here, the phrase “dual action” means that the caster includes first and second wheel section spaced apart along a horizontal axis that can rotate in either the same direction or in opposite directions to move the chair 10 along a trajectory or to rotate the base about an axis through the center of the vertical post 350. Thus, caster 352 may be controlled to rotate the chair base and also move the chair 10 and therefore could be used to move the chair to any clear location within an office space (e.g., to a charging location).

After charging is complete, the chair processor 58 may be programmed to control the motors 320 and 322 to move the chair into a welcoming position within an office. Thus, for instance, referring again to FIG. 8, a chair 10 may be moved away from a charging station and back to a location that faces an egress into the space 30 to welcome a user to sit down in the chair upon entry into space 30.

In yet another embodiment, a robot type charging assembly may move to a charging location relative to a chair assembly 10. To this end, see FIG. 14 that shows a robot type or mobile charging assembly 370 akin to the station described above with respect to FIG. 9. The difference in FIG. 14 is that assembly 370 includes powered wheels 372 and casters 374 that can be used to move station 370 about within an office space to assume a charging position with respect to a chair assembly base 12 that includes spoke electrode pads 232 and 234. Although only one powered wheel is shown in FIG. 14, an assembly 370 could have two spaced apart and independently controlled powered wheels 370 so that the assembly could rotate about one stationary wheel by powering the other.

In some cases the robot recharging assembly 370 may be tethered (e.g. connected by a cord) to a wall or other power receptacle. In other cases the recharging assembly 370 may be wireless and be able to move about more freely. In this case, it is contemplated that a stationary robot charging station would be provided for the robot and the robot itself would include a rechargeable battery or other type of power source. Here, the charging station for the robot may include an electrode configuration similar to the electrode configuration on the chair base spokes so that the electrode set on the robot could perform double duty (e.g., to charge the robot power source from the robot charging station and then to charge the chair power source). In this regard, see FIG. 15 that shows a robot recharging station 380 that includes electrode pads 382 and a form that can link the pads 382 to the electrodes on the recharging robot 370. Once the robot battery is charged, the robot can leave charging station 380 and move to the chair base spokes as shown in phantom

In some cases a robot power assembly may be located in each office and associated with a specific chair 10 so that the control process can be relatively simple. In other cases it is contemplated that there may be one or a small number of robot recharging stations located on a floor of an office building travel and recharging robots may roam around the floor recharging any chair battery that is not fully charged or at least at a threshold charge level. In some cases, where a battery provides charge level data to a chair processor 58, the chair processor 58 may transmit a charge request to a facility server 54 and cause that server to control one of the roaming robots to start a recharging process. Thus, for instance, a subset of recharging robots may be located at recharging stations while other robots are out recharging chairs.

In cases where a robot or a chair including motorized casters or other motive means are provided, the chair processor or a robot processor would track the amount of charge on its rechargeable battery and would conserve enough energy to move the associated assembly to a recharging station prior to complete discharge in at least some embodiments. Thus, for instance, in the case of a chair that consumes power, processor 58 would shut down functions and features that use power when a threshold charge on the chair battery is reached. The next time conditions exist for recharging (e.g., a user leaves an office), the chair processor 58 would move the chair to the recharging position and commence charging.

In some embodiments it is contemplated that a chair mat may operate as a chair charging station. In this regard, see FIG. 16 that shows a charging mat 28 in top plan view. Mat 28 is divided into twelve different charging zones 38 where adjacent charging zones have different polarities. For instance, in FIG. 16, cross hatched zones may have a positive polarity and non-cross hatched zones may have a negative polarity when powered. Here, whenever an electrode or electrical probe on a chair assembly 10 contacts one of the zones 38, an electrical connection between a charging source and the chair probe may be formed. In this regard, see also FIG. 17 where a chair base 12 is shown resting on a charging mat. In the illustrated example, in addition to the components described above, base assembly 12 includes five charging probes 390. Here, each charging probe is similarly constructed and operates in a similar fashion and therefore only one of the probes 390 will be described in any detail. An exemplary probe includes a probe housing 394 that is mounted to an undersurface of one of the base spokes proximate a caster 15 that is at the distal end of the spoke. The housing includes a downward opening and an electrical probe type electrode 392 a is mounted in the opening. In the illustrated embodiment, the probe 392 a is mounted for movement along a vertical axis so that the lower distal end of the probe 392 a can be raised and lowered to separate from the mat 28 there below and to make contact with the mat, respectively. Probe 390 includes a motor 396 that can raise and lower the probe 392 a like a piston.

Referring still to FIGS. 16 and 17, the pattern of positive and negative charging zones 38 is designed based on the spacings between the probe assemblies 390. To this end, the pattern of zones 38 are designed so that at least two of the probe assemblies 390 reside above different polarity (e.g., positive and negative) zones at any time that the chair assembly 10 is located on the mat 28. In this regard, see that the chair base 12 is represented in phantom in four different locations with respect to the mat zones 38 and that in each case, even when the chair 10 is only partially on top [of the mat 28, at least two of the probe assemblies reside above different polarity mat sections.

In the FIGS. 16 and 17 embodiment, it is contemplated that a switching mechanism within chair assembly 10 may be controlled to change the charging polarity of each of the probes 390 so that, regardless of which zone 38 a probe is over, the probe may be connected to the zone and commence charging when desired. Thus, for instance, in FIG. 16 two probes 392 c and 392 d are shown aligned with positive and negative zones 38, respectively. In this case the switching mechanism would be controlled to make probe 392 c positive and probe 392 d negative. If the chair assembly 10 were moved to the location associated with probes 392 c′ and 392 d′ so that those probes were aligned with negative and positive zones, respectively, the switching mechanism would be changed to make probe 392 c′ and probe 392 d′ negative and positive, respectively.

As described above in at least some cases the probes are controlled to extend to make an electrical contact during charging and may be retracted to break that contact when not charging. In this regard, see for instance probes 392 a in FIG. 17 that are shown extended and probes 392 b that are shown retracted. In some cases only two of the probes may be extended at any time. Here, for instance, where the position of the probes is known due to a sensor in the chair or in the space that includes the chair, if first and second probes are known to be located over positive and negative zones, respectively, only the first and second probes may be extended to make a charging contact with the mat 28.

In some cases a chair assembly 10 may only include two extending probes that are arranged to always align with different polarity zones when the chair 10 is on the mat 28. In other cases where there are five probes, even if all five probes are extended during a recharging cycle, the chair processor 58 may only use two of the probes during recharging.

In some cases the mat 28 may have much smaller zones so that different polarity probes may be spaced much closer to each other and still result in probe alignment with different polarity zones. For instance, see FIG. 18 where a mat 28 includes smaller adjacent different polarity zones and where the probe structure includes a single probe assembly 400 that includes a housing 402 mounted to the undersurface of one of the base spokes, a motor 404 for extending and retracting probe electrodes and two electrodes 392 e and 392 f. Here the probe electrodes are much closer and therefore can be drive by a single small motor 404 to extend and retract when appropriate.

Referring yet again to FIG. 18, in at least some embodiments, instead of including a motor 404, the probe assembly 400 may simply include spring loaded probes 392 e and 392 f where springs in the probe assemblies push the probe electrodes out to that distal ends thereof engage the upper surface of the mat 28 there below at all times. Here, the spring force would be minimal and the distal ends of the probes would be rounded so that friction between the top surface of the mat 28 and the probe would be minimal.

In still other embodiments other motorized and extendable probes may be mounted to other chair assembly components. For instance, probes may be extendable along a vertical axis upward from one or both of the arm rest members 53 (see again FIG. 1 to make contact with pads on the undersurface of a table top or the like (e.g., see again FIG. 11). Alternatively, probes may be mounted to seat 16 and extend rearward to laterally there from to contact charging pads or the like on a wall or other upright structure.

In still other embodiments power may be provided to a chair assembly 10 to recharge a battery via a wireless and contactless power delivery system. For instance, supply 22 may be recharged by way of near-field or non-radiative techniques including inductive charging from a power source, resonant inductive charging from a power source, capacitive coupling charging from a power source, magnetodynamic coupling charging from a power source, and the like, or radiative techniques, including optical charging from a power source, microwave charging from a power source, etc. When employing recharging by way of a direct connection to a power source, the wired connection can be established manually by a user or automatically by one of the systems described herein.

Referring to FIGS. 4 and 19, a wireless charging receiver 24 can be located at various positions within, on, or affixed to chair assembly 10. When employing wireless recharging, the wireless charging receiver 24 and a wireless charging transmitter located remote from the chair assembly 10 can be positioned relative to one another manually by a user or automatically by one of the systems or methods described herein. The wireless charging transmitter can be located on the underside of a desk, in a functional surface (e.g., within a mat 28) on which the chair assembly 10 sits, affixed to a wall, or in any other location suitable for providing wireless charging to the chair assembly 10.

In some embodiments, the wireless charging receiver 24 can be an inductive charging receiver. In other embodiments the wireless charging receiver can be a resonant inductive charging receiver. In still other embodiments, the wireless charging receiver 24 can be a radiative charging receiver. In any case, the charging receiver can be located in or affixed to an arm assembly 20, including the top, front, side, or bottom of the arm assembly 20 (see FIG. 19), in or affixed to a seat assembly 16, including the top, front, side, or bottom of the seat assembly 16; in or affixed to a back assembly, including the front, top, side, or back of the back assembly 18; in or affixed to the base assembly 12, including the bottom, top, front, back, or side of the base assembly 12 (see FIG. 4). In certain embodiments, the wireless charging receiver 24 can be located beneath at least a portion of the base assembly 12 and in a position where a user's feet may not contact the wireless charging receiver 12. In this arrangement, it is contemplated that the wireless charging receiver 24 can be configured to move in a coordinated fashion with the seat assembly 16, so that as a user rotates the seat assembly 16, the wireless charging receiver 24 rotates so that its positioning relative to the user's feet remains substantially the same.

In a recharging position, the distance between the wireless charging receiver 24 and the wireless charging transmitter can be any distance over which a charge suitable for recharging the rechargeable power supply 22 is capable of being transmitted. For certain applications, the distance between the wireless charging receiver 24 and the wireless charging transmitter can be at least ⅛ inch, at least ¼ inch, at least ½ inch, at least 1 inch, at least 2 inches, at least 3 inches, at least 6 inches, at least 9 inches, at least 1 foot, at least 1.5 feet, at least 2 feet, at least 3 feet, or at least 5 feet. For certain applications, the distance between the wireless charging receiver 24 and the wireless charging transmitter can be at most 12 feet, at most 10 feet, at most 8 feet, at most 6 feet, at most 5 feet, at most 4 feet, at most 3 feet, at most 2.5 feet, at most 2 feet, at most 1.5 feet, at most 1 foot, at most 10 inches, at most 8 inches, at most 6 inches, at most 4 inches, at most 2 inches, at most 1 inch, or at most ½ inch.

In a recharging position, the center of the wireless charging receiver 24 and the wireless charging transmitter can be aligned with one another or can have an offset. As one of skill in the art will appreciate, the efficiency of the wireless charging may be impacted by the alignment of the wireless charging receiver 24 and the wireless charging transmitter.

In many of the embodiments contemplated by this disclosure, for various reasons, a chair user may not want to have the rechargeable battery in their chair assembly 10 charging while they are seated in the chair, generally within the space associated with the chair or even in the same room as the chair. In these cases, in at least some embodiments, a chair sensor or some type of room sensor may sense when occupancy within a space (e.g., the seat, the surrounding area or the room containing the chair) around the chair and may only commence a charging cycle when no one is in the space. For instance, if the space is the chair itself, a presence or weight sensor on the chair itself may generate data useable by the chair processor to determine if a person in seated in the chair. As another instance, a room camera 100 (see again FIG. 8) or a camera 102 associated with a computer display 413 in a room that includes the chair may generate images that can be examined by a facility processor 54 to ascertain if anyone is in the space proximate the chair or even within the room 30 associated with the chair 10. Here, when no one is in the space, the facility processor 54 may transmit a vacant signal to the chair processor 58 causing the chair processor to commence a recharging process. For instance, in the case of an automated charging process like the one described above with respect to FIGS. 8, 9 and 10, processor 58 may control the caster motors (e.g., 320) to move the chair over to charging station 210 and commence charging. Here, if a person enters the space while a charging cycle is occurring, the charging process may be halted and processor 58 may control the caster motors to move the chair 10 back into a welcoming position.

Again, here, when charging is occurring, some visual indication may be provided such as illuminating an LED (see again 263 and 265 in FIG. 9) and when charging ceases a different LED or visual indicator may be illuminated to signal to the user whether the system is charging. Other charging and non-charging indicators are contemplated. For instance, in some cases, a speaker 415 (see FIG. 6) may be provided in a surface of the chair that can announce the charging status. For example, when charging commences, the speak may annunciate “Battery is charging” and when charging ceases the speaker may annunciate “Charging has stopped”. In certain cases, the speaker may also notify the user that the “Chair requires charging” at some point in the future.

In some cases charging may only commence after processor 58 or some other system processor recognizes that no one has been in the space associated with the chair for at least some threshold period of time (e.g., 15 minutes) or until a user associated with the chair has left some larger space such as a facility which would indicate that the user is likely away for an extended period of time. In still other cases the processor 58 may only commence recharging when no one is in the space associated with the chair during some specific time of day. For instance, recharging may only occur at night and on weekends when no one is in a chair associated space.

In some embodiments, at least one of the facility based sensors 93 (see again FIG. 7) or the portable device sensors 89 may be able to determine the location of a specific person associated with a chair or office in space. For instance, a wrist mounted portable user device may receive signals from a plurality of access points 69 within a facility and may be able to triangulate its location based on signal strength or some type of statistical analysis. The device and, hence, the device user's location may be transmitted to the facility based processor 54 for further processing. Here, in at least some cases where a chair charges when no one is in the space associated with the chair, when the person associated with the chair or office comes within some vicinity of the chair or office (e.g., arrives on a floor of a building that includes the chair after having been away), the system may cause the chair to interrupt the charging process and move into a welcoming position automatically. Thus, for instance, when a chair user rises from a chair 10 and leaves her office, after a threshold period in which the user is outside the office, the chair may be controlled to move to a charging station in the office and commence a charging function. If the user leaves the building in which the chair is located, the charging function may continue. If, then, the user reenters the floor of the building that the chair is on prior to the end of the recharging process, the recharging process may be interrupted and the chair may assume the welcoming position.

In still other embodiments, the rechargeable battery may be recharged by a mechanical motion associated with chair components that move as a chair user moves the chair components. The mechanical motion can be a motion that is intended for a purpose other than recharging, but can incidentally also be used to provide some recharging power, such as a wheel connected to a power generator that provides electric power when a user moves the chair assembly 10 or a power generator that converts some of the force from a user sitting down in the chair assembly 10 into electric power.

In the embodiments described above as including chair components that make direct electrical connection to recharging probes or electrodes, in at least some embodiments the direct connections may be replaced by wireless power transfer components such as inductive coupling antenna or the like. For instance, in FIGS. 9 and 10, the electrodes and pads 224 and 226 and 232 and 234 may be replaced by inductive coupling antenna. Here, as larger antenna usually results in faster transfer of power, the coupling arrangements may be relatively large.

In the embodiments described above as including chair components that employ recharging by way of wired or wireless power by way of an arm assembly 20, it is contemplated that a single arm assembly can house the necessary components. In the embodiments described above as including chair components that employ recharging by way of a direct connection with an arm assembly 20, it is contemplated that an electrode 280 can be placed some distance beneath a comfort surface of the arm assembly 20. In one aspect, the comfort surface can be compressed by the motion of a pad 272 and 274 which can establish a direct electric connection once the comfort surface has been sufficiently compressed. In another aspect, the comfort surface can have holes or grooves that allow an extension electrode coupled to the pad 272 and 274 to penetrate past the comfort surface and make contact with the electrode 280.

In the embodiments described above as including chair components that employ recharging by way of a direct connection with a seat assembly 16, a back assembly 18, or an arm assembly 20, it is contemplated that the charging can occur via a comfort surface of the seat assembly 16, the back assembly 18, or the arm assembly 20, where the comfort surface comprises a material that can suitably receive an electric charge for the purposes of recharging the rechargeable power supply 22. Examples of such a material include, but are not limited to, a smart fabric, electrically conductive polymers, and the like.

In the embodiments described above as including chair components that employ recharging by way of a direct connection, it is contemplated that the electrodes for receiving the recharging can be located on a portion of the chair assembly 10 that is not contacted by a user during normal use.

Referring to FIGS. 7, 17 and 20, this disclosure provides a method 600 of recharging a chair assembly 10 comprising a rechargeable power supply 22 and a set of moveable electrode probes 292 a that are used with a power delivery mat 28. At decision block 602, one or more of the system processors (see again FIG. 7) receiving data from one or more sensors associated with a chair 10 or the space associated with the chair 10 determine if a user is located in or near the chair assembly 10. For instance, images from a camera 100 (see also FIG. 8) may be used to determine if anyone is in the office including the chair 10. If the answer at decision block 602 is YES, then control loops back through decision block 602. If the answer at decision block 602 is NO, control passes to process block 604. At process block 604, chair processor 58 controls the probe motors to move two or more charging probes 392 a located above two or more charging zones 38 into a charging position. At process block 606, processor 58 determines the polarity of the two or more charging zones. At process block 608, if the polarity of each probe that contacts one of the charging zones is the same as the polarity of the charging zone, control passes to block 610. If, however, at block 608 the polarity of the probes that contact the charging zones is not the same as the polarity of the charging zones, the polarity of the charging zones or the polarity of the probes 392 a must be changed to match the polarities. For instance, the probe polarities can be changed using a simple switching mechanism within the chair assembly 10 itself. As another instance, a facility processor 54 may control a switching mechanism within the mat 28 to change the polarity.

Continuing, at process block 610, recharging commences. While the chair battery is recharging, the method 600 can include parallel decision blocks 612 and 614. At decision block 612, processor 58 determines if the rechargeable power supply 22 is fully charged. If the answer to decision block 612 is NO, control loops back up to process block 610. If the answer to decision block 612 is YES, then control proceeds to process block 616. At decision block 614, the method 600 includes determining if a user has moved in or near the chair assembly. Here, data from any of several different chair, office or facility sensors may be used to discern the current location of a chair user and/or other persons or at least the relative juxtapositions of the user and/or other persons with respect to the chair assembly 10.

If the answer to decision block 614 is NO, then control loops back up to process block 610. If the answer to decision block 614 is YES, then control proceeds to process block 616. At process block 616, the recharging cycle is ended and processor 58 controls the probe motors to move the charging probes 392 a into their stored and non-charging positions.

The process described above with respect to FIG. 20 may be altered in many different ways depending on the hardware included in a chair assembly but would take the general form of receiving some form of sensed data from system sensors, using the received data to discern whether or not someone is located within a space associated with a chair assembly 10, if no one is in the space associated with the chair assembly, commencing a charging process, if a chair battery is fully recharged, ceasing the charging process and if someone enters the space associated with the chair during the recharging process, halting the recharging process.

For instance, in a case where a chair includes an inductive or otherwise wireless power coupling antenna or the like and is used with an inductively coupling floor mat, wall mounted mat, under table top mat, etc., the FIG. 20 process would simply skip from block 602 to block 610 without performing blocks 604, 606 and 608 as the probe extension and polarity checking steps could be skipped.

As another instance, in a case where a chair is used with a stationary charging station akin to the one described above with respect to FIGS. 8 through 10 and the chair assembly includes a motive mechanism for moving the chair assembly from a use position to a charging position, the FIG. 20 process may be altered to include sub processes whereby the chair assembly 10 is moved prior to and after recharging. To this end, see the process 700 in exemplary FIG. 21 where, at block 702, system processors determine if charging is required and if an area or space associated with a chair assembly 10 is occupied. If charging is not required or the space associated with the chair 10 is occupied, control continues to loop through decision block 702. Once the conditions of block 702 are met control passes to block 704 where chair processor 58 moves the chair 10 to the recharging station and at block 706 a recharging connection is made between the station and the rechargeable chair battery. At block 708 recharging commences. Blocks 710, 712 and 714 in FIG. 21 are akin to blocks 212, 214 and 216, respectively, in FIG. 20. After charging is terminated at block 714, control passes to block 716 where processor 58 moves the chair assembly 10 away from the charging station and into a welcoming position as described above.

Referring still to FIG. 21, the two decisions associated with block 702 may be taken in any order. Thus, for instance, the need for charging may be considered first and only if charging is needed, the occupancy of the space associated with a chair assembly 10 may be considered. In the alternative, the occupancy of the space may be considered first and the need for recharging may only be considered if the space is unoccupied instantaneously or for at least some threshold period of time.

Similarly, the two decisions associated with blocks 710 and 712 may be sequential rather than parallel. For instance, the recharging decision block may be considered prior to the occupancy block 712 so that recharging continues once it is commenced until either recharging is complete or a user manually discontinues the recharging process. The FIG. 21 method 700 can optionally include providing a visual indicator that the rechargeable power supply 22 is being recharged during recharging.

FIG. 22 illustrates a method 800 whereby a recharging robot (e.g., motive recharging stations) is employed to recharge a chair battery. Prior to process 800, it is assumed that the chair processor 58 or some other system processor 52, 54, etc., has received data from the rechargeable battery 22 and has determined that the battery requires recharging. It is also assumed that the system processors have determined that other conditions required for recharging have occurred. For instance, the processors may have determined that the space associated with the chair assembly is unoccupied. As another instance, the processors may have determined that a time period (e.g., between midnight and 4 AM) scheduled for recharging chairs has occurred. Many other recharging conditions and sets of conditions and circumstances are contemplated.

In FIG. 22, once processors have determined that recharging is required and that conditions for recharging have occurred, at block 802 system processors generate an initiate recharging control signal which is sent to a recharging robot (see 370 in FIGS. 14 and 15). At block 804, the robot 370 is controlled to move to a recharging position relative to the chair assembly 10 and a recharging connection is formed at block 806. At block 808 recharging commences. At block 810, control continues to loop up to block 808 until recharging is complete at which time control passes to block 812 and recharging is terminated. At block 814 the recharging robot moves away from the chair assembly 10. The robot may either move back to a robot recharging station if the robot needs an additional charge or if there are no other chair assemblies requiring a recharge or may move on to a next chair assembly that needs recharging.

Referring to FIG. 23, a method 900 in which a chair user manually moves a chair assembly into a recharging position relative to a recharging assembly is illustrated. At block 902, once one or more system processors determine that recharging is required, an indication is provided to the chair user that recharging is required. The indicating step 902 may include providing an indication selected from the group consisting of a visual indication, an audio indication, a haptic indication, an olfactory indication, and combinations thereof. For instance, a motor in a chair assembly 10 may be used to vibrate a portion of the chair assembly to indicate required recharging. As another instance, in some cases a signal may be provided to a chair user's computer (see 420 in FIG. 8) causing the computer 420 to present a pop up window with a warning that recharging is required. As yet another instance, in some cases a signal may be transmitted to a user's wearable device (e.g., a wrist mounted computer device) causing the wearable device to generate a recharge warning sound, to vibrate or to present a text warning or notification that recharging is required. Many other application modules may be used to provide a warning to recharge.

At block 904, when appropriate, the chair user manually moves the chair to a recharging station and at block 906 recharging commences. As a user attempts to place a chair in a recharging position, the system may provide feedback to the user indicating whether or not a suitable connection has been made and recharging commenced. For instance, the speaker 415 (see again FIG. 6) may generate a voice signal indicating “Recharging commenced” or something akin thereto. In other cases, after connection is made via manual movement, recharging may not commence for a short period to allow the user to be located at a location away from the station (e.g., leave the office including the chair). In this case, once a suitable charging connection is made, speaker 415 may generate a voice signal indicating “Connection made, recharging will commence in five minutes”. In still other cases, after connection is made via manual movement, recharging may not commence until the space associated with a chair assembly is unoccupied and charging may automatically cease when anyone enters the chair associated space. Here, the speaker may generate a voice signal indicating “Connection made, charging will start when you leave your office” or some similar suitable indication. Connection and charging indications may be provided via other application modules associated with the chair assembly 10 or provides as part of a facility or a portable user device.

In at least some embodiments it is contemplated that two or more chair assemblies including rechargeable batteries may be located in a single office, conference space, common area of a facility, etc. In this case, it is contemplated that a single recharging station or recharging robot may be used to recharge multiple chairs in sequence. Here, each chair processor 58 may be programmed to determine its own battery charge state or condition and may provide that information wirelessly on a regular basis to a facility server or processor 54. The facility processor 54 can then identify which chair in a space is least charged and commence a recharging process for that chair first, recharging other chairs subsequently as a function of their relative charging states. Thus, for instance, where there are eight chairs in a space, facility processor 54 may send a signal to the processor 58 associated with the least charged of the eight chairs to move to a single charging station within the space to commence recharging. Then, after the first chair battery is recharged, processor 58 may move that chair away from the station and processor 58 may commence a second move and recharging cycle with a second of the chair assemblies.

In at least some cases where there are many chairs within a space, the facility processor may be programmed to keep at least a subset of the chairs in a fully recharged state at all times. Thus, in the case of an eight chair space, regardless of the lowest level of chair charge in the space, processor 587 may control recharging so that four of the chairs are fully charged at all times if possible. For instance, if one chair is only 10% charged, three are fully charged and one is 70% charged, processor 58 may be programmed to charge the 70% charged chair prior to the 10% charged chair. Conversely, in some cases, processor 58 may be programmed to charge first a chair with a lower or lowest existing charge.

Where there are two or more chair assemblies in one space, the system may indicate the chair with the greatest charge level to a user to help the user select a most charged chair. For instance, where one chair is 100% charged and a second is 30% charged in a space, processor 58 may cause the 100% charged chair to assume a welcoming position and the 30% charged chair to assume a side position (e.g., a position at a greater physical distance from an entry into the space). As another instance, if there are eight chairs in a space and four of the eight are fully charged while one is 50% charged and the other three are each 20% charged, the system may indicate the four fully charged in some fashion when a person enters the space. For instance, when a first person enters the space, a motor in each of the four fully charged chairs may cause the chair to vibrate or to rotate back and forth slightly about the center support post under the seat to allow the user to select any of the four fully charged chairs. In the alternative, one of the four fully charged chairs may vibrate, rotate back and forth, etc., to indicate a full charge.

In the above example, once the four fully charge chairs are occupied, when a fifth person enters the space, the fifth chair that is 50% charged may be controlled to indicate that it is the next most fully charged chair, and so on. In still other embodiments, where a subset of chairs is charged above a threshold level and another subset are not, the system may control the chairs to arrange the subset of chairs charged above the level about a conference table and to locate the other chairs at a side location as an indication of relative charge.

In some cases the system may assess chair battery charge and provide some indication thereof to the user. For instance, again, a chair processor 58 may transmit chair charge level to another system processor like facility processor 54, portable device processor 52 or a processor located within a space based computer 420 in FIG. 8 and the receiving processor may indicate charge status. In this regard, see FIG. 24 that shows a computer display screen shot 429 that indicates chair charge status at 422. Here, the charge status information may be relatively simple, (e.g., % charge still available) or may be far more complex. For example, a system processor 58 may be programmed to calculate a remaining charged time available prior to discharge assuming use of chair features in a fashion similar to recent use. See in this regard the additional time indicator at 424 in FIG. 24. As another example, a system processor 58 may be programmed to calculate the amount of recharging time required for a chair battery to reach a charge level sufficient for the chair to operate in a fashion similar to recent use for another one hour period and may provide an indication of that required recharging time as at 426 in FIG. 24. Similarly, assuming a chair user typically works until 5 PM each evening, a system processor 58 may be able to detect how much additional time would be required to recharge a battery to a charge level sufficient to provide power until 5 PM and provide an indication of that required time as at 428 in FIG. 24. By indicating additional time to charge to a level for powering the chair for a specific amount of time, the chair user may decide to take a recharging break for a few minutes while the chair recharges. Then, the chair may fully charge at some other suitable time (e.g, after 5 PM in the above example).

Feature Modules

Referring to FIGS. 25 though 27, chair assembly 10 can include one or more feature modules 26 (e.g., sensors or application modules (actuators)). It should be appreciated that the illustrated locations of the feature modules 26 are only examples of the locations they can occupy, and the feature modules 26 can be located in positions others than those shown in the FIGS. 25 through 27. The one or more feature modules 26 can be located on, within, or affixed to a base assembly 12, a support assembly 14, a seat assembly 16, a back assembly 18, or an arm assembly 20. It should also be appreciated that certain feature modules 26 are more appropriately located in certain positions, based on the function of that feature module 26. For example, a feature module 26 that is intended to interact with the back of a user is more suitably positioned in the back assembly 18 than elsewhere in the chair assembly 10. The feature modules 26 can be sensing modules, which can make a measurement relating to a user, the environment, a chair condition, and combinations thereof, application modules, which perform an application relating to the user, the environment, a chair condition, or combinations thereof, or combined sensors/application modules, which perform the functions of both a sensing module and an application module.

In at least some embodiments, a feature module 26 can be swappable, such that one type of feature module that is located in a particular location on the chair assembly 10 can be removed and replaced with either a replacement of the same type of feature module 26 or a different type of feature module 26. In this way, the chair assembly 10 is customizable to the user's desired experience and can be modified post-market as a user's desired experiences change.

Referring to FIG. 28, a schematic diagram showing the general electronic configuration of a chair assembly 10 is shown including chair processor 28 and exemplary feature modules 26 generally, which can include any of one, a subset of or all of the listed modules.

The user input module can be configured to transmit a user input signal to the processor 58 representative of the user input. The user input signal can be a simple signal indicating that a user is actuating the user input module or can have some on-board processing capacity in order to send a more complex signal that is more indicative of a user's intention. As an example of the simple signal, a user input module in the form of a button could communicate a binary signal to the processor indicating whether the button is being actuated or not. As an example of the more complex signal, a touch pad could identify a user activity on the touch pad as representing a specific command and can communicate that command to the processor rather than the user activity itself.

A remote user input module can be remote from the chair assembly 10 and serve the same function as an internal user input module. For example, a device containing a user-based processor, a facility-based processor, or a global processor can serve as a remote user input module.

The processor can then send a signal to the power supply that causes the power supply to stop emitting power or causes the power supply to be electrically isolated from the feature modules. It is therefore evident that the particular embodiments disclosed above may be altered or modified and all such variations are considered within the scope and spirit of the invention. Accordingly, the protection sought herein is as set forth in the claims below.

Referring to FIG. 31, a chair assembly 10 can be positioned in front of a work surface in a position where a user could use a keyboard 510 on the workstation table or desk 32. The desk 32, the keyboard 510, or both can include one or more remote sensors 512 configured to sense one or more of the properties discussed herein. On top of the desk 32, a monitor 514 can be placed, with an optional camera 516 affixed to the top of the monitor 514 for optically sensing a user that is occupying the chair assembly 10. Also on the desk, a microphone 540 can be positioned for sensing audio from a location remote from the chair. While specific locations are shown for the remote sensors 512, the camera 516, and the microphone 540, it is contemplated that they can be positioned anywhere that they can serve their respective purpose.

In other embodiments, referring to FIG. 32, it is contemplated that recharging probes 446 and 448 can be located within the one or more casters 15 affixed to the chair base 12, such as between two wheels of the caster 15. The chair base 12 is shown resting on a charging mat 28 having charging zones 38 of alternative polarity. The recharging probes 446 and 448 can be spaced to ensure that they are always interfacing with charging zones having opposite polarity, such as neighboring charging zones 38 having opposite polarity.

In other embodiments, referring to FIG. 33, it is contemplated that recharging-probe-containing wheels 440 and 442 of one or more casters 15 affixed to the chair base 12 can be used for recharging. In this embodiment, the wheels of the caster 15 are themselves recharging probes. The chair base 12 is shown resting on a charging mat 28 having charging zones 38 of alternative polarity. The recharging-probe-containing wheels 440 and 442 can be spaced to ensure that they are always interfacing with charging zones having opposite polarity, such as neighboring charging zones 38 having opposite polarity.

As mentioned briefly above, in some embodiments it is contemplated that a personal device like a cell phone or a wearable device like a wrist band based device may perform various methods that are used with a chair assembly 10. In at least some cases it is contemplated that a chair assembly and other system devices (e.g., feature modules like sensors and actuators) may be able to perform many different functions and processes and that a user may select one or more different processes at her preference to be performed. Here, in at least some cases, a user may access an on line applications web site and down load applications to the user's personal device for controlling chair and facility affordances. For instance, the applications may include heating applications that can be used to control heating devices located in the chair seat, backrest, arm rests, etc. In this case, a chair user may control chair heating elements manually via a user input screen on the user's personal device or the user's personal device processor may automatically control chair component heating elements based on sensed data or a programmed heating cycle. As another instance, the applications may include different types of backrest movement applications that can be downloaded to the user's personal device for control backrest position either manually or automatically based on sensed data or user preferences. For example, a user may use an application to select different backrest positions at different times of the day and then, each day, the user's personal device processor 52 may control the chair to cycle through the specified positions when the user's device is proximate the chair and the user is located in the chair. Thus, in some cases a user's personal device processor may control the chair based on any of a large number of user selectable applications that are downloaded from a web site or the like.

Referring again to FIG. 8, in other embodiments a chair user may use a computer 427 (see FIG. 8) proximate a chair 10 to access applications on a web site and download those applications to either the computer itself to control operations or to the chair processor 58 to control chair and other operations. Again, here, the chair 10 may be purchased with hardware to perform a large number of applications, only a small number of which are enabled or loaded into system processors and thereafter, a user may be able to change the applications run by any of the system processors to fit user preferences.

As discussed elsewhere, the chair assembly 10 can operate in an occupancy sensing modes. Referring to FIG. 1, the occupancy sensing can be achieved by an intelligent fabric located on the top surface 21 of the seat assembly 16, the front surface 35 of the back assembly 18, or the top surface 55 of the forearm rest member 53; a pressure sensing module located at the front edge portion 23, rear portion 45, first or second lateral portions 41 and 43 of the top surface 21 of the seat assembly 16, the central portion 27, the first or second lateral portions 29 and 31, or the upper or lower portion 141 and 37 of the front surface 35 of the back assembly 18; or the top surface 55 of the forearm rest member 53. A presence sensing switch as described herein can occupy the same locations set forth for the occupancy sensing module.

In response to a user input indicating availability or a sensed condition that the processor is programmed to interpret as indicating availability, the processor can send an availability signal indicating that the user of the chair is available to the facility-based processor, a separate user's user-based processor, or any other processor remote from the chair assembly 10. This feature allows a facility manager to quickly assess the portion of the workforce that is available to accomplish a specific task or allows a co-worker to determine whether an unscheduled meeting would be welcomed by the user.

This disclosure contemplates that the aforementioned sensing modules and processors can be utilized to monitor activity of a user, such as movement of a user, sound produced by a user, including talking, and the like.

This disclosure contemplates that the aforementioned sensing modules and processors can be utilized to measure the frequency or magnitude of a user's muscle action.

This disclosure contemplates that the aforementioned sensing modules and processors can be utilized to determine the state of the chair assembly 10, such as the height, various angles, rotational movements, and the like.

This disclosure contemplates that the aforementioned sensing modules, application modules, and processors can be utilized to achieve a therapeutic benefit for a user. For example, the processor can use sensing modules to monitor one or more properties of a user that are related to the user's health, the processor can use application modules to alter one or more properties of a user that are related to the user's health, or a combination thereof.

This disclosure contemplates that the aforementioned sensing modules, application modules, and processors can be utilized to improve a comfort level of a user. The improvement in comfort level can be automatic, in response to a sensed comfort level that can be determined by a processor using signals from one or more sensing modules that sense a property that is associated with comfort. The automatic comfort improvement can be perceptible by a user or imperceptible by a user. The improvement in comfort level can be user-controlled, in response to a user input signal from a user input. The user-controlled comfort level improvement gives a user the feeling of heightened control over their comfort.

In at least some embodiments it is contemplated that operating characteristics of the chair may be controlled in a manner that encourages a chair user to behave in desirable or healthy ways. For instance, it is known that a posture in which a user engages fully the upright backrest is, in general, a relatively healthy posture for a person sitting in a task chair for a period of time. It is also known that many people enjoy having heat applied to their backs for various reasons including therapy, comfort, etc. In a simple case, referring again to FIG. 1, heat may be applied to at least a portion of the front surface of a backrest assembly 18 at one or more locations that a typical chair user's back cannot contact unless the user is sitting in a generally upright position. For instance, heat may be applied to a lower section 37 of a backrest surface below a lumbar region which can only be contacted by a user's lower back when the user has her buttocks pushed back toward the rear portion of the chair seat 16 which is consistent with an upright posture. As another instance, only the central lumbar region 27 of the backrest assembly 18 may be heated so that a chair user is required to sit back against that central section to feel the heat. In other cased one or more of a shoulder support region 141 and/or left or right lumbar regions 29 or 31 may be heated if appropriate to encourage proper posture.

In still other embodiments heat may be applied to any one or more portions of the top surface of the seat assembly 16 in order to encourage proper posture. For example, see again FIG. 1 where heat may be applied to the rear portion 45 of the top surface of the seat assembly to encourage a seated user to move her buttocks rearward or heat may be applied to one or the other of left and right portions 41 and 43 of the top surface of the seat assembly 16.

Referring to FIG. 5, the chair assembly 10 can include motion application modules in the form of motors 39 that can actuate parts of the chair assembly 10. Motors 39 can also be located anywhere on a chair assembly 10 that application modules are shown.

The motors 39 can be positioned in the chair assembly 10 at locations where the chair assembly 10 is traditionally configured to move in response to manual motion, such as on a post member 17 that extends upward from the base member 13, at a joint of a support for the arm assembly 20, at a joint between the back assembly 18 and the rest of the chair assembly 10, locations where motion is described elsewhere herein, and the like. The motors 39 can be coupled to a mechanical mechanism that is traditionally located within a chair assembly 10, such as a hydraulic actuator, an arm articulation mechanism, a back recline mechanism, and the like.

The motors 39 can also be positioned at locations in the chair assembly 10 to provide motion at locations that are not traditionally associated with motion of a chair assembly 10, such as a motor 39 positioned to selectively extend a lumbar support in response to a posture sensing signal indicative of a need for lumbar support, a motor 39 positioned to selectively extend an upper back support in response to a posture sensing signal indicative of a need for upper back support, a motor 39 positioned to selectively move the seat assembly 16 backward to bring a user's back into better contact with the back assembly 16 in response to a posture sensing signal indicative of a user not engaging the back assembly 18, and the like.

While some motors for moving a chair assembly and adjusting chair assembly component juxtapositions are described above, other motor locations, arrangements and combinations are contemplated. For instance, in some cases one motor may be provided on the post between a chair base and the seat support structure for rotating the seat and other components supported by the support structure to different angular orientations relative to the base. Here, a second motor may be mounted to a caster for moving the chair about in a space. In this case, the first and second motors should be able to move and angularly orient the chair assembly in essentially any location and orientation within a space that is not blocked by other affordances. Many other motor combinations for moving a chair are contemplated.

As another example of a motion application module, the chair assembly can include one or more airbags that inflate in response to a signal from a processor to move the top surface 21 of the seat assembly 16 or the top surface 55 of the forearm rest member 53 substantially upward and downward, or the front surface 35 of the back assembly 18 substantially forward and backward. The airbags can also provide movement along any of the contours of the surfaces described herein. Airbags can be located at the front edge portion 23, rear portion 45, first or second lateral portions 41 and 43 of the top surface 21 of the seat assembly 16, the central portion 27, the first or second lateral portions 29 and 31, or the upper or lower portion 141 and 37 of the front surface 35 of the back assembly 18; or the top surface 55 of the forearm rest member 53.

In some cases chair settings may be altered as a function of a user's weight, size, height or other body dimensions (e.g., leg length, arm length, torso dimensions) that may be sensed prior to or while the user is supported by the chair. For instance, in some cases where airbags are provided in a seat or backrest assembly, the amount of air in the airbags may be adjusted based on a measured weight of a chair user. In other cases, where a user has particularly long arms, chair arm rests may be moved forward to support a user's arms in an optimal fashion.

It is also known that in many cases, while an upright posture is generally healthy, movement of a chair user's body during a several hour period is also generally advantageous. In at least some embodiments chair conditions may be changed over time to encourage movement and other healthy behaviors. For instance, in the case where heat can be applied to different locations on the front surface of a backrest assembly or the top surface of a seat or both, in at least some cases a system processor (e.g., 52, 54, 58, etc.) may be programmed to cycle heat to different locations on the surfaces thereby encouraging the seat user to move to continue to feel the applied heat. Thus, referring again to FIG. 1, heat may first be applied to the lower back portion 37 of backrest assembly 18 for 15 minutes. After the first 16 minute period, heat may be applied to the top portion 141 of the backrest assembly 18 for the next 15 minutes. Then, heat may be applied to the left portion 29 of the backrest assembly for 15 minutes and then applied to the right hand portion for 15 minutes and then the cycle of moving heat may be repeated. The heat cycle described herein is only exemplary and many other heat cycles are contemplated.

While heated surfaces are one good way to encourage healthy behavior of a chair user, other actuators and application modules are contemplated that achieve a similar purpose. For instance, referring again to FIG. 1, in at least some embodiments, some type of vibrating element may be located at different locations on the front surface of the backrest assembly 18 or the top surface or an edge of the seat assembly 16 that can be felt when a portion of a user's body contacts the surface(s). Again, for instance, a vibrating mechanism may be mounted at the lower back region 37 or the upper back region 35 to encourage optimal posture. As another instance, a cooling element or some device that cools may be provided at any surface location to encourage optimal posture or any other positional behavior by a chair user.

In still other cases one or more sensors may be used to ascertain if a chair user's behavior is optimized and if not, the chair may disallow certain chair features until the behavior is optimized. For instance, in the case of posture and application of heat to encourage optimal posture, a system processor may only apply heat when a user is sitting in one of several pre-designated postures and may turn off the heat when the user is not sitting in one of the pre-designated postures. Similarly, vibration or any other haptic effect may be available in select pre-designated postures. In some cases, heat, vibration, and other haptic effects may be available when a user changes postures regularly.

As yet one other instance, heat, vibration or any other pleasing effect may only be applied for specific durations and may be turned off for other periods and until some required activity occurs. For instance, to encourage a chair user to periodically get up and take a short walk, chair heat may only be enabled for 45 minutes at a time and then be off for 15 minutes encouraging a break. In other cases the heat may remain off until a chair user has gotten up and left the chair for at least 5 minutes. Thus, if the user remained in the chair for one and a half hours straight without getting up, heat would be applied for 45 minutes and then be turned off for the remaining 45 minutes (e.g., until the user got up for at least five minutes). In this case, if the user got up and took a walk immediately after the initial 45 minutes, the heat would be re-enabled after the user is absent for the 5 minute interim period.

In at least some embodiments it is contemplated that a chair assembly 10 may include components so that at least some aspects of the chair assembly are automatically adjustable to optimally support a chair user that is in a less than optimal position on the chair assembly. In particular, because motors are added to at least some chair embodiments, the motors can be used to drive chair components into supporting positions relative to a user. To this end, see FIG. 34 that shows a chair backrest assembly 18 that includes first and second motors 448 and 452 that are arranged at upper 456 and lower 454 portions of the backrest assembly 18. Here, the motors are shown schematically and would be linked to the assembly 18 so that motor 448 can be controlled to push the top end of the backrest assembly 18 forward and pull the top end backward to adjust the forward-rearward position of top end 456 and motor 452 could be controlled to push the bottom end 454 of backrest assembly 18 forward and pull the bottom end rearward to adjust the forward-rearward position of the bottom end 454. For example, the top end 456 may be able to move through a range of between two inches and ten inches.

Similarly, the bottom or lower end 454 may be able to move through a range between two and ten inches. In this case, if a chair user is slouching with his buttocks near a central portion of chair seat 16 and spaced away from the rear portion of the seat, the rear portion 454 of the backrest assembly may be pushed forward so that a front surface thereof contacts the lower portion of the user's back and provides some support. The upper portion 456 may similarly be moved about to support the upper portion of a chair user's back automatically in a similar fashion.

In still other cases it is contemplated that a chair assembly may move components automatically to make contact with and provide support to a user's back or other portions of the user's body when a user maintains a less than optimal position long term. The chair assembly may also be controlled to apply an appealing effect like heat or vibration. In some cases, it may then, over time, move back into a position or positions consistent with a preferred back position to encourage the user to reorient himself into a different posture. Thus, for instance, referring again to FIG. 34, in some cases the lower portion 454 of the backrest assembly 18 may be moved forward 8 inches to contact a user's lower back surface. Then, heat may be applied to the lower portion of the backrest front surface (see 37 in FIG. 1).

After a set time interval, e.g., one minute, of heat application, the lower portion of the backrest assembly may be moved rearward by one inch while still applying heat. If the user moves his lower back rearward to maintain contact with the heated portion of the seat, after another minute, the lower portion of the backrest assembly may be moved another inch rearward, again, encouraging movement of the user's lower back rearward and toward an optimal posture position. This coaxing would continue in an effort to cause the user to move into a different and preferred posture. If, at any time a user does not follow the coaxing action, the action may be reversed to again provide support for the user in the user's selected posture and the coaxing may either end or recommence.

Referring to FIG. 35, in another embodiment, a single post 516 can extend down from a central portion of the base assembly 12 and a wireless charging receiver 518 can be attached to the single post. An advantage of this arrangement is that the user's feet typically do not occupy the space near to the single post 516. Another advantage is that the height of the wireless charging receiver 518 is not changed as a user adjusts various chair heights and positioning.

Referring to FIG. 36, a variation on the embodiments shown in FIGS. 9 and 10 is illustrated, where the chair assembly 10 can be recharged via a single base assembly spoke member 520. Two or more electrode pads 522 and 524 can be positioned on the top surface portions of the spoke member 520 at its distal end. Still referring to FIG. 36, the chair assembly 10 can engage a station assembly 526 that includes positive and negative electrodes 528 and 530 (shown in phantom in FIG. 36) positioned to provide electrical contact with the electrode pads 522 and 524. This embodiment can include any of the features described elsewhere with respect to a spoke member-based electrode pad and station assembly, but configured to recharge the chair via a single spoke member 520.

Referring to FIG. 37, a variation on the embodiment shown in FIG. 11 is illustrated, where wireless recharging is deployed. Here, wireless charging transmitters 532 and 534 are located on an undersurface 275 of the table top member 270 at spaced apart locations generally proximate a front edge of member 270. Referring also to FIG. 19, wireless charging receivers 24 can be located within or affixed to arm rest members of the arm assemblies 20. In this case, to charge a chair battery, a user would first adjust chair arm members to a position that enables sufficient coupling between the wireless charging receiver 24 and the wireless charging transmitters 532 and 534. The alignment can be provided as described elsewhere herein. Again, some table structure (e.g., legs or other guide members) may be provided to help the user align the arm members and associated wireless charging receivers 24 with the wireless charging transmitters 532 and 534.

Referring to FIG. 38, a chair assembly 10 on a chair mat 28 is shown from the underside of the chair mat 28. Referring also to FIG. 4, the chair assembly 10 can have a wireless charging receiver 24 affixed to the base assembly 12. Referring to FIG. 38, the mat 28 can include one or more wireless charging transmitters 536 (shown in phantom in FIG. 38) for wirelessly transmitting power to the chair assembly 10. This arrangement can be utilized for any wireless charging receiver 24 mounted to the underside of the chair assembly, including the arrangement shown in FIG. 35. The alignment between the wireless charging receiver 24 and the wireless charging transmitter 536 can be any alignment described herein that is suitable for providing sufficient coupling to transmit power.

In at least some embodiments the system processors may control chair operations as a function of sensed conditions of the chair user. For instance, based on different temperatures sensed at different locations within the seat 16, backrest assembly 18 and the arm rest members 20 either instantaneously or over time as the temperatures change, one of the processors may be programmed to discern either that a chair user is in pain or will likely experience pain in some part of her body (e.g., lower back, left arm, leg, etc.). Here, based on the discerned physiological parameter, the processor may control motors, heat elements, etc., in the chair assembly in some fashion calculated to eliminate perceived pain or to avoid likely pain. For instance, chair motors may be automatically controlled to change relative juxtapositions of chair components to change the physical positioning of the chair user in some calculated fashion. As another instance, chair sensors or images from a camera in the ambient may generate data that can be used to determine that a chair user is fidgeting and likely uncomfortable. In this case, a heating element in the lumbar region of the chair may be activated to apply heat in an effort to the user's lower back to increase comfort.

In cases where different people use the same chair at different times as in conference rooms, in hotelling spaces, etc., in some cases chair activities and functions may be automatically adjusted based on user identity. Thus, for instance, if one user prefers a set of five functions and a specific set of adjustments on her chair and a second user prefers a set of four other functions and a second specific set of adjustments, in at least some cases user identity and location may be determined (e.g., via triangulation of a user's personal computing device, an identification badge that includes an RF tag or some type of ID transmitter, biometrics, etc.) and, just prior to or after a user sits in a chair, the chair features may be adjusted and functions used to control chair components and features.

In some cases a chair may be programmed to operate differently at different times of day. For instance, in the morning a chair may apply heat, in the afternoon, after a lunch break, the chair may apply cooling and in the late afternoon, the chair may perform some vibration or massage activity. Similarly, a chair may be programmed to perform different functions based on different activities a user is performing or participating in or to perform different functions based on what a user is scheduled to be doing at different times. For instance, when a user is scheduled to be in a private focused session, the chair may perform heating, vibration, massage, support in a lounging position as opposed to an upright position, etc. When the same user is scheduled to be in a conference room with several other people during a collaboration session, the chair may force or strongly encourage an upright posture and may not perform massage or vibrating activities. Other schedule based control of the chair assembly 10 is contemplated and to support such functions, one or more system processor 52, 54, 58, etc., may have access to scheduling information maintained by a facility or enterprise server.

Worker wellbeing is an important focal point for many organizations because of the cultural, environmental, and economic implications wellbeing may have. Wellbeing—often characterized as an individual's health, happiness, satisfaction, physical state, and/or mental state—may be measured and assessed in a variety of ways. In certain circumstances, a worker's physical environment may impact various aspects of wellbeing. For example, aspects of wellbeing that may be impacted by a worker's physical environment include optimism, which may be essential for fostering creativity and innovation; mindfulness, which may allow a worker to engage more fully with the task at hand; a realization that a worker can be authentically himself or herself; a sense of belonging or connecting to others; a feeling that professional contributions have a meaning or a sense of purpose; and an ability to experience a workplace full of vitality that encourages workers actively to experience multiple aspects of the physical environment.

Wellbeing may be improved by communicating with a worker in a manner that seeks to increase his or her movement during the day, to engage more fully with his or her work, and to create a supportive and positive environment, among other things. In particular, communicating with a worker, may allow him or her to identity ways to optimize his or her interaction with the physical environment in a way that improves optimism, mindfulness, authenticity, belonging, meaning, or vitality. Various embodiments of the disclosed system collect and analyze data relevant to a worker's wellbeing and communicate information back to the worker in an effort to improve his or her wellbeing.

FIG. 39 illustrates a system 600 for providing information to a user of an article of furniture. System 600 may be used in a variety of ways including collecting and analyzing data from users, encouraging or rewarding users, assisting users in maintaining mental engagement with their work, facilitating improved communication between users, and helping users identify or create ideal work environments. System 600 includes a plurality of users 602, displays 604, sensors 610, chairs 614, and tables 616. System 600 also includes gateways 620 and processor 630. System 600 includes a variety of places including an office building 650 and a personalized work space 652. In particular embodiments, system 600 may include any number of suitable users 602, displays 604, sensors 610, and articles of furniture, including but not limited to chairs 614 and tables 616. Similarly, system 600 may include any suitable number of gateways 620 and processors 630 or other system components.

Users 602 include a collection of workers affiliated with an organization, who have a variety of roles. At least one user 602 j may have responsibility for the organization. This organizational user 602 j may be a facility manager, a facilities planner, an operations manager, a purchasing professional, or any professional with responsibility for space utilization, worker wellbeing, worker retention, or other pursuits valuable to the organization. Users 602 may be associated with one or more displays 604. For example, user 602 a, 602 c, 602 d, 602 f, 602 g, and 602 h are each associated with a display 604 that is included in a personal computer such as a tablet, laptop, or mobile phone. User 602 f is associated with a display 604 in a wearable computer such as a watch or glasses. User 602 i is associated with a display 604 that is embedded in table 616. User 602 j is associated with a display 604 configured at his personal workstation. Users 602 b and 602 e aren't illustrated with associated displays. These users may have a personal computer such as a tablet or laptop, a wearable computer such as a watch or eyewear, or may additionally or alternatively rely on displays embedded in their surrounding environments.

Several of chairs 614 and tables 616 include a coupled sensor 610. These sensors may be embedded in the chairs 614 and tables 616 and may or may not be perceivable to users 602. In some embodiments, some or all furniture within system 600 may have one or more sensors 610.

Personalized work space 652 includes sensor 610 configured to sense information about users 602 in or near work space 652. Including sensor 610 within work space 652 allows system 600 to sense information about a particular user 602 even when he is not in physical contact with chair 614 or other furniture within work space 652.

Gateways 620 allow sensors 610 and other devices such as the tablets, laptops, phones, and wearables mentioned above to relay information to processor 630. Processor 630 analyzes information from sensors 610 and these devices and may provide information to users 602. Information from processor 630 may include collective information regarding a group of users 602 or may include information about a particular user 602. Processor 630 may send information to an individual user, a group of users, or to the organizational user 602 j. Information from processor 630 may be displayed on displays 604.

System 600 may include a variety of additional or alternate components that facilitate communication with users 602. For example, system 600 may include additional sensors, gateways, displays, and furniture. System 600 may include greater or fewer users 602. These users 602 may all be located within building 650 or may be positioned at a variety of locations within an organization's campus. Alternatively, one or more users 602 may be working in a location geographically remote from one or more of the other users 602. For example, organizational user 602 j may be located in building 650 on a central campus, while user 602 a is located at a second location and user 602 i is located at a third location. The number of locations within system 600 may be equal to, greater than, or less than the number of users 602. The number of chairs 614 and tables 616 within system 600 may be correlated to the number of users 602, including a historical number of users 602, a current number of users 602, or an anticipated future number of users 602. Chairs 614 may include office-style task chairs, guest chairs, lounge style chairs, stools, and any other known furniture designed to accommodate a seated user. In various embodiments, a variety of furniture equipped with one or more sensors 610 may be included in system 600, including chairs, stools, panels, lounge style furniture such as sofas, tables, desks, shelving, or storage units. Although FIG. 39 illustrates via dashed lines possible paths of data transmission between particular system components, the sensors, displays, and personal devices described in conjunction with FIGS. 39 through 49 may be able to transmit data to any number of system components, including processors, gateways, other sensors, other displays, and other personal devices, regardless of the presence of an illustrated dashed line. FIG. 40 illustrates a block diagram 700 that portrays additional details of a communication system, similar to system 600. Block diagram 700 includes sensors 710 a-c, a power source 712, a gateway 720, a server 736, a processor 730, software 732, and storage 734.

Sensors 710 sense data about the environment and/or users, similar to users 602 described in conjunction with FIG. 39, and provide data to server 736 via gateway 720. Sensors 710 may communicate with gateway 720 over a local area network (LAN) through a wired or wireless connection. For example, as illustrated, sensors 710 a and 710 c send data to gateway 720 absent any hard wired connection, instead sending data wirelessly. Sensor 710 b is wired to gateway 720 and transmits data through this wired connection. Sensor 710 b may also receive power through its wired connection with gateway 720. Sensor 710 a receives power from power source 712. Power source 712 may provide power in a variety of ways, for example, through a low voltage transformer or a battery, from harvested energy, wirelessly through inductive coupling or resonant inductive coupling, or in any other known way. Sensor 710 c does not have a separate power source and may instead rely on piezoelectric technology or other technology to provide sufficient energy for transmitting information to gateway 720. Depending on the embodiment, sensors 710 may employ a range of technologies. For example, sensors 710 may detect heat or pressure changes, may detect touch, or may detect changes in a variety of health indicators. Certain sensors 710 may rely on Bluetooth, iBeacon, or near field communication technology. In some embodiments, sensors 710 may include an accelerometer.

Sensors 710 may be present in a variety of locations within an organization's environment. Sensors 710 may be embedded in an article of furniture, such as a chair or table, similar to chairs 614 and table 616 in FIG. 39. In some embodiments, sensors 710 may be embedded in or coupled to a wall, partition, ceiling, of floor. Sensors 710 may also be associated with a user, present, for example, in a user's identification badge or mobile communication device (e.g., a smart phone, in a writs worn device, etc).

Gateway 720 relays information to server 736 and may be coupled to server 736 via a LAN or wide area network (WAN). Gateway 720 may be any device suitable to receive, aggregate, and/or relay information from sensors 710 a-c, including, for example, a wireless router or a Room Wizard™. Gateway 720 may include existing technology affiliated with other services of an organization or may be provided to an organization specifically for use with sensors 710. In some embodiments, more than one gateway 720 may be used to optimize performance. For example, the number and/or positioning of gateways may depend on the number and/or positioning of sensors 710.

As information from one or more sensors 710 reaches server 736, software 732 may determine how the information is processed. In this embodiment, a software module 732 a commands processor 730 to perform a variety of tasks, including those functions described in conjunction with FIG. 41. For example, processor 730 may analyze incoming data related to a user's posture, occupancy, mental engagement, or other factors. Processor 730 may make determinations or conclusions about a user or group of users based on incoming data. Processor 730 may also relay information or send conclusions to a user or group of users. Incoming data from sensors 710, other incoming data or inputs, conclusions, and other data may be stored in storage 734.

In various embodiments, server 736 may be a virtual server or may represent a cluster of servers. Some or all portions of the block diagram may be located physically on site at an organization's location and some or all may be stored remotely in the cloud. For example, in one embodiment, server 736 may physically include processor 730 while software 732, software module 732 a, and storage 734 are located in a remote or cloud server. In another embodiment, only software 732 or storage 734 may be located in a remote or cloud server. Software module 732 a may additionally communicate with a variety of other servers, processors, hardware, and software located in server 736 or in other servers or other locations. For example, software module 732 a may communicate with a second server to ensure that a user's calendar or reservation information is up-to-date.

FIG. 41 illustrates a system 800 for providing information to a user of an article of furniture, similar to systems 600 and 700 described above. In particular embodiments, system 800 senses information about a user and solicits feedback from the user to confirm conclusions related to the sensed information. System 800 includes users 802 a and 802 j, a display 804, sensor 810, and a chair 814. System 800 also includes a gateway 820 and a processor 830.

User 802 a is a worker affiliated with an organization. User 802 a may have a variety of responsibilities. User 802 j is also affiliated with the organization and has responsibility for the organization in some capacity. For example, user 802 j may be a facility manager or human resources professional.

User 802 a is associated with display 804. In this embodiment, display 804 is included in user 802 a's assigned tablet. In other embodiments, display 804 may be included in a variety of devices or environmental locations.

User 802 a typically has display 804 with him throughout the workday including when he is seated in chair 814. Chair 814 may be user 802 a's assigned chair, or may be unassigned, and is equipped with sensor 810. In one embodiment, sensor 810 may include the ability to sense changes in pressure. In another embodiment, sensor 810 may additionally include an accelerometer and the ability to sense movement of the chair. Sensor 810 may be powered via a battery, a harvested energy source, or in any variety of known ways.

In some embodiments, chair 814 may include multiple sensors 810 that each has different capabilities. Possible additional sensors 810 a are illustrated in dashed lines. In one embodiment, sensors 810 a coupled to the back of chair 814 may include accelerometers and sensors 810 a coupled to the seat of chair 814 may include the ability to sense pressure and/or heat changes. The number of sensors 810 coupled to chair 814 may depend on cost, manufacturing considerations, organizational requirements, or other factors.

Sensor 810 senses information about user 802 a including when he sits down in chair 814 and the duration of his stay. Sensor 810 senses information about how user 802 a is sitting in the chair including whether he is relatively still or whether he has begun to move or shift in chair 814. Sensor 810 also senses posture information, including whether user 802 a is sitting upright, reclining, perching near a front edge chair 814, or other information. Sensor 810 sends some or all of this data to processor 830 via gateway 820.

Processor 830 processes this data and draws one of more conclusions based on the data. For example, processor 830 may conclude that chair 814 is occupied. Occupancy determinations may also include more specific conclusions. For example, processor 830 may conclude based on the rate of occupancy that chair 814 is in a preferred location within the business enterprise, that chair 814 is a preferred seat for workers of the business enterprise, and/or that chair 814 is a preferred seat for user 802 a. Processor 830 may conclude that user 802 a has been sitting for an extended period of time and would benefit from a change in posture, for example, by standing up. When the data from sensor 810 indicates that user 802 a had previously been sitting relatively still and has now begun to shift or fidget in his chair 814, processor 830 may conclude that user 802 a has become distracted or is beginning to lose focus on his current task. Conversely, user 802 a may be a consistent “mover” in his chair during the workday and any reduction or slowing of movement may indicate that user 802 a is no longer engaged with his work. Similarly, processor 830 may conclude that user 802 a is struggling to remain mentally engaged because he is reclining in his chair despite engaging in a task that usually keeps him sitting upright. In some embodiments, processor 830 may conclude from an increase in body or ambient temperature that user 802 a would benefit from a change in location. Processor 830 may reach a variety of conclusions based on the data for a user or users depending on the data and any software present in system 800, similar to software 732 described in conjunction with FIG. 40.

Conclusions made by processor 830 are based on objective data from sensor 810. Processor 830 may rely on software or other applications stored on the same server or in a remote location to draw conclusions about the objective data from sensor 810. In some embodiments of system 800, processor 830 will send one or more instructions to an application affiliated with user 802 a for display on display 804. This instruction may cause display 804 to display information based on the objective data. The instruction may additionally or alternately solicit information from user 802 a related to the conclusion of processor 830. In some embodiments, user 802 a can provide any solicited input via a yes/no answer, through a multiple choice style answer, or by entering free standing text. For example, display 814 may pose one or more questions to user 802 a about occupancy, posture, or focus, including:

-   -   Is this your preferred location?     -   Is this your preferred seat?     -   What is your preferred seat?     -   Do you prefer to sit upright or recline in a lounge position for         your current type of work?     -   Have you been sitting most of the morning?     -   Have you been predominantly sitting today?     -   Have you been predominantly sitting this week?     -   Are you feeling engaged with your work?     -   Are you feeling less engaged with your work than you were 15         minutes ago?     -   Is your environment allowing you to focus?     -   What is the ideal environment for your current type of work?     -   Has an environmental distraction made it more difficult for you         to focus?     -   Has an environmental distraction made it more difficult for you         to focus now that it was 15 minutes ago?     -   What is the ideal environment for the work you expect to do         later today?     -   What is the ideal environment for the majority of your work?     -   When do you most need to deviate from your ideal environment?

User 802 a can use display 804 as an interface to provide input and answer questions. Information solicited from user 802 a and related to user 802 a's subjective understandings and perceptions may then be relayed by user 802 a's tablet or other device associated with display 804 back to processor 830.

Upon receipt of user 802 a's subjective data, processor 830 can develop an output about user 802 a based on his objective and subjective feedback. For example, processor 830 may determine that user 802 a has been shifting in his seat and he confirmed his change in engagement through his subjective feedback; processor 830 may then send an output to user 802 a encouraging him to take a break, go for a walk, or change locations. As another example, processor 830 may determine that user 802 a has been sitting relatively still for a longer than recommended time and has confirmed his focus has begun to wane; processor 830 may then send an output to user 802 a encouraging him to stand up and continue working.

In an additional example, processor 830 may determine that the body temperature or ambient temperature near user 802 a is rising and he has confirmed that he prefers cooler environments; processor 830 may send an output to user 802 a encouraging him to change location and may even include a suggestion about a possible preferred location. These and other outputs may be displayed for user 802 a via display 804. Other outputs may encourage other changes or actions to improve user 802 a's physical or mental health or engagement.

In some embodiments, system 800 may include, and processor 830 may have access to, additional information about user 802 a including identity, type of responsibilities, current tasks, and preferred work settings generally or for specific tasks. User 802 a may provide this information initially or on an on-going basis. Processor 830 may also have access to information about a variety of work environments within the organization. As a result, in embodiments where processor 830 has access to information about user 802 a's current task and preferred environments for specific tasks, processor 830 may be able to provide a recommendation to user 802 a that he should consider moving from chair 814 to a particular alternative location more suitable for the task. In certain embodiments, this recommendation may occur as soon as system 800 detects that user 802 a has begun a new task or may occur upon concluding that he is losing focus in his present location.

In certain embodiments, processor 830 may send an output about user 802 a based on the objective and/or the subjective data to user 802 j. In embodiments of system 800 that include a group of workers like user 802 a, processor 830 may send an output to user 802 j about the group of workers based on the objective and/or subject data of each member of the group or about the aggregated members. User 802 j may use information received from system 800 to evaluate occupancy within the organization, to assess productivity associated with specific locations or tasks, group mental engagement, group wellbeing as it relates to health and satisfaction, or other factors. This information may be especially valuable to user 802 j when one or more users are working from remote locations.

System 800 may learn about user 802 a over time. For example, system 800 may come to determine based on user 802 a's objective and subjective data that when user 802 a starts to shift in chair 814 in a particular window of time, for example, before lunch, he is likely to be losing focus, while when user 802 a starts to shift in chair 814 in a different window of time, for example, after lunch, he is not losing focus. Or system 800 may sense user 802 a shifting posture to a position perched on the front edge of chair 814 and user 802 a may confirm that he is losing focus when he shifts to “perch” while completing one task but not another. System 800 may receive the same objective data from sensor 810 in either scenario, but may receive different subjective feedback from user 802 a regarding his degree of focus or engagement with his work depending on the circumstances. This may allow system 800 to forego or limit the instances where it solicits feedback from user 802 a. In this embodiment, when system 800 receives objective data from sensor 810, it may not solicit additional feedback from user 802 a, instead relying on subjective feedback received on a previous day or days, and sends an output for display encouraging user 802 a to take action. For example, when the sensor data indicates a change and system 800 predicts user 802 a may be losing focus, it may encourage him to stand up and continue working, seek an alternative work location, or take a break.

FIG. 42 illustrates a method 900 of providing information to a user of an article of furniture, similar to systems 600, 700, and 800 discussed above. In particular embodiments, method 900 is directed toward sensing information about a user and soliciting feedback from the user to confirm the sensed information. Method 900 begins at step 910 by sensing a first data set about a user of an article of furniture through the use of a sensor. In certain embodiments, the sensor is coupled to an article of furniture such as a chair or table. In other embodiments, the sensor may instead be coupled to a wall, partition, ceiling, or floor such that it can collect information about a user of furniture within the environment. The first data set in certain environments is data collected by the sensor without knowledge and/or input from the user, similar to the objective data discussed above in conjunction with FIG. 41.

Method 900 continues with steps 920 and 930 that include sending the first data set to a processor and generating a conclusion based on the first data set, respectively. The processor may receive data from the sensor disclosed in step 910. In certain embodiments, the processor may receive the data via a gateway. Upon receipt of the data from the sensor, the processor is able to generate one or more conclusions. Depending on the type of information collected by the sensor, the processor's conclusions may include determinations about the furniture's usage or occupancy, about the duration of occupancy, about the user's posture, and/or about the user's mental focus or engagement with his work. For example, the first data set may indicate that the user has begun to shift or move within the chair and the processor may conclude that the user is beginning to lose focus on his current task. In various embodiments, the first data set may include any type of information that can be sensed about a user using the sensor.

Step 940 includes generating a second data set about the user through input by the user, where the input relates to the conclusion. In various embodiments, information is solicited from the user that relates to the conclusion described in step 930. The user may be able to receive questions and provide feedback via a display associated with a personal device, such as a computer, laptop, tablet, mobile phone, watch, glasses, clothing, or other device. The display may also be positioned somewhere within the user's environment, for example in a table or wall. The solicited information may include questions designed to provide subjective feedback and/or confirmation on the conclusion. For example, if the processor's conclusion includes a determination that the user is beginning to lose focus on his current task, the input solicited by the user may be focused on the user's level of focus or engagement with his work. This input comprises a second data set about the user. In certain embodiments, the second data set may include a range of information about the user, including the user's preferences regarding his preferred work environment, his preferred work environments for specific tasks, his preferred ways of improving his perceived wellbeing, his preferred methods to increase his physical activity, his preferred ways to increase his mental focus and engagement, and other preferences regarding his work and work environment.

Method 900 continues with steps 950 and 960 that include, respectively, sending the second data set to the processor and generating an output about the user based on the first data set and second data set. In certain embodiments. the output about the user based on the first data set and second data set includes a recommendation for the user, for example, a recommendation the user change posture or location to increase his engagement with his work. The output may additionally or alternatively be based on the conclusion discussed above in conjunction with step 930. In particular embodiments, the output may include a metric about the conclusion. For example, the system may sense a user routinely selecting a certain seat or a particular setting for a chair or table, a selection which the user validates through user input and the generation of the second data set; the output in this circumstance may be tailored to recommend the desired or a related seat or setting to the user in the future.

Step 970 concludes method 900 by sending this output to the user. In various embodiments, this output is displayed to the user via the display described in conjunction with step 940.

Method 900 may additionally or alternately include other steps. For example, in certain embodiments, the method may proceed fully or partially with respect to a group of users and some or all of the data about the group may be sent to a facilities manager. In some embodiments, outputs about a user or a group of users may be sent to an organizational user, such as a facilities manager. Outputs sent to an organizational user (an organizational output) may include the user outputs previously sent to one or more users. In some embodiments, the information included in an organizational output may include aggregated information about the number of users within the system, partial or overall occupancy rates of furniture and/or particular environments within the system, usage rates of the communication system, types or numbers of outputs sent to users within the system, or any other information that may be stored within the system.

A related method may include identifying a selected position for a sensor within a work environment that is appropriate to sense a first data set about a user of an article of furniture within the work environment; placing the sensor in the selected position; creating a network between at least the sensor, a processor, and a device configured to solicit a second data set from a user; ensuring the sensor is configured to send the first data set to the processor; and ensuring the processor is configured to receive the first data set from the sensor and the second data set from the device, to generate an output about the user based on the first data set and the second data set, and to send the output to the user.

An additional, related method may include creating a system for collecting information about a group of users by providing a plurality or group of furniture in a work environment, providing a group of sensors that are positioned within the work environment and are configured to sense individual data sets about each of the users of the furniture; and providing a processor configured to receive the individual data sets from the sensors, to generate a plurality or number of conclusions, where each conclusion is based on one of the individual data sets, to receive input data sets, where each input data set results from input from one user and relates to one conclusion, to generate outputs, where each output is based on at least one of the individual data sets and one of the input data sets, and to send one or more outputs to one or more of the users.

The type of information included in a user output and/or organizational output may also be determined based on the nature of sensed information and/or information input by the user. FIG. 43 includes a schematic diagram 980 illustrating how information collected by a sensor or sensors or provided by a user or group of users may be shared with an organizational user. On the left side of schematic 980, information is more generic and potentially less sensitive. Generic data might include information regarding whether a chair is occupied by any user during working hours and may exclude any identifying information about the user. Moving from left to right data becomes less generic; it starts to become more personal in nature and more sensitive. Moderately personal information may include information about where a user prefers to work during the day or his or her preferred conference room and the corresponding amenities or settings. A user may identify this data as moderately sensitive and may allow it to be shared, in some cases without his identifying information (e.g., in the aggregate). On the right side of schematic 980, data is highly personal and potentially highly sensitive. Highly personal data might include a health characteristic of a user as measured by a sensor in a chair. A user may identify this or other data as highly sensitive and may not allow it to be shared with anyone under any circumstances.

The scope of data shared with an organizational user in some embodiments is illustrated with bubble 982. Bubble 982 includes generic information for single users and groups of users and moderately personal information for groups of users; it does not include any highly personal data associated individual users or groups of users in the system. Bubble 984 illustrates the type of data shared with an individual user in some embodiments. Bubble 984 includes highly and moderately personal information about the user, but does not include generic information about users or groups of users. In certain cases, bubbles 982 and 984 may overlap or take on other shapes within schematic 980.

FIG. 44 illustrates a system 1000 for providing information to a user of an article of furniture, similar to systems described in conjunction with FIGS. 39-43. In particular embodiments, system 1000 provides information to a user, similar to users 602 and 802 described in conjunction with FIGS. 39 and 41, for the purpose of encouraging, motivating, coaching, changing, or rewarding behavior. System 1000 includes users 1002 a and 1002 j, displays 1004 a and 1004 j, sensors 1010, chair 1014, table 1016, gateway 1020, and processor 1030. Any number of users, displays, sensors, furniture, gateways, processors, and other components may be included in various embodiments.

User 1002 a is a worker affiliated with an organization and may have a variety of responsibilities. User 1002 j is also affiliated with the organization and has responsibility for the organization in some capacity, for example, as a facility manager, real estate planner, human resources professional, wellbeing coach, or health professional. In some embodiments, users 1002 a and 1002 j may be located in the same building or on the same campus. In other embodiments, users 1002 a and 1002 j may be geographically remote from one another.

User 1002 a is associated with display 1004 a. In this embodiment, display 1004 a is included in user 1002 a's watch. In other embodiments, display 1004 a may be included in a variety of environmental locations or devices, such as a laptop computer, tablet computer, personal phone, or other wearable device.

Chair 1014 is equipped with sensor 1010. Similar to the sensors described previously in conjunction with FIGS. 39, 40, 41, and 42, sensor 1010 may sense changes in pressure, temperature, movement, other environmental changes, and/or a variety of health factors. Because sensor 1010 may sense changes in pressure, temperature, or movement of chair 1014, it is able to collect information that may be useful to user 1002 a regarding his posture, the duration he has been sitting, or the likelihood that he might benefit from a change in location, activity, or posture. As stated with respect to sensor 810 and chair 814, in some embodiments chair 1014 may include more than one sensor and these sensors may be positioned anywhere on chair 1014, for example sensors may be embedded in or coupled to a seat, back, headrest, arms, pedestal, base, or casters.

As sensor 1010 collects data about user 1002 a it transmits some or all of the data to processor 1030 via gateway 1020. Sensor 1010 may transmit data continuously as it is collected or at regular or irregular intervals. The timing of sensor 1010's transmissions may be established based on the purpose of system 1000, the needs of system 1000's users including users 1002 a and 1002 j, and/or determined by a user including organizational user 1002 j. In some embodiments, sensor 1010 may transmit information to a processor in an alternative way. For example, gateway 1020 may be omitted or sensor 1010 may share information with an intermediate collection device that relays the information to processor 1030.

Processor 1030 processes the data it receives from sensor 1010. Processor 1030 also receives and processes one or more inputs from organizational user 1002 j. Relying on data received from sensor 1010 and input received from organizational user 1002 j, processor 1030 generates one or more conclusions, which may include an output suitable to send to user 1002 a. In certain embodiments, input from organizational user 1002 j may direct the types of outputs user 1002 a should receive. For example, an input may direct processor 1030 to provide encouragement or motivation to change behavior.

One or more inputs from organizational user 1002 j may be received by processor 1030 as it receives data from sensor 1010. Inputs may alternatively or additionally be received prior to or after any data from sensor 1010. In various embodiments, organizational user 1002 j may provide one or more inputs to processor 1030 on a regular basis, for example, a new input or inputs may be received by system 1000 every quarter, month, week, or weekday. The interval of the inputs may be tailored to current business indicators of the organization or other factors.

The content of the inputs may also be tailored. For example, in circumstances where financial indicators of the organization are positive, the output might include a reward that has a cost to the organization, such as offering the user a cup of coffee or a meal “‘on the house” or paid for by the organization. In particular embodiments, the content of the input from organizational user 1002 j may include information about particular users or groups of users. Further, the input from organizational user 1002 j may also include information on the threshold or requirement that must be achieved by a user to receive the reward. Once processor 1020 determines that data from sensor 1010, associated with 1002 a, has surpassed the threshold or satisfied the requirement, processor 1020 generates an output to send to user 1002 a. For example, one input from organizational user 1002 j may include a condition that if a user has been sitting for longer than a set period of time, such as 2 hours, he or she should be encouraged to change posture and stand up. In this example, processor 1030 receives this input from organizational user 1002 j; once processor 1030 receives data from sensor 1010 that user 1002 a in chair 1014 has been sitting for more than the prescribed period of time, processor 1030 generates a conclusion that user 1002 a had been sitting for the prescribed period of time and should now change posture. Processor 1030 then sends the output to user 1002 a.

In an additional example, another input from organizational user 1002 j may include information designed to encourage or reward user 1002 a under certain circumstances. For example, organizational user 1002 j may provide an input that user 1002 a may be rewarded for continuous focus on a given task. The input may outline that user 1002 a may be rewarded by an offer for a snack or beverage, a message of encouragement from user 1002 a's superior or team, a change in work location or duration, or any variety of other positive feedback or accolades.

Inputs may depend on multiple aspects of a data set or data sets attributed to user 1002 a in certain embodiments. For example, the input from organizational user 1002 j may direct the processor to recommend that the user take a break and stretch after he has been sitting for longer than a prescribed time and has begun to fidget in chair 1014. Once sensor 1010 data indicates that user 1002 a has been sitting for longer than the prescribed time and has begun to shift in chair 1014, processor 1030 generates an output that can be sent to user 1002 a encouraging him to get up and take a break and stretch.

In some embodiments, processor 1030 may rely on additional data sources in generating an output, including, for example, a personal or corporate calendar, local weather information, information from other places within the organization, data input by user 1002 a similar to the input described in conjunction with FIG. 41, or any useful data source relevant to the organizational user input or the system user. For example, when processor 1030 receives data from sensor 1010 that user 1002 a has been sitting in chair 1014 for a set number of hours each day, for a certain number of consecutive days or days within a prescribed time period, and processor 1030 receives information from a corporate calendar that the present working day is the last day before a corporate holiday or from a meteorological database that the weather has unexpectedly changed for the better (or worse), the output to user 1002 a may encourage him to leave the office earlier than his typical departure time.

When processor 1030 receives information about local weather, it might also provide user 1002 a with an output including a recommendation to take a walk outside the organization's building if data from sensor 1010 indicates he has been sitting for the majority of the afternoon. In some embodiments, organizational user 1002 j may provide a group of inputs that include a variety of different rewards or encouragements. Processor 1030 may determine which input to base its output on randomly or according to some other factor, such as user location, user preference, user responsibilities, or user interests.

Additionally, a particular output may be directed to all members of a group or team. For example, both user 1002 a and organizational user 1002 j may be included within the same group or team and may receive the same output (as illustrated in FIG. 44, organizational user 1002 j's workstation also includes sensor 1010 coupled to table 1016 in his workstation and he may be an active, individual participant in system 1000).

After processor 1030 generates an output for user 1002 a, it transmits the output to user 1002 a's watch including display 1004 a via system 1000 in a manner similar to those discussed in conjunction with FIG. 40. In addition, system 1000 may detect user 1002 a's personal device or devices based on proximity or user 1002 a may register his device with system 1000 in accordance with certain embodiments. User 1002 a's personal device may display a message based on the output on display 1004 a and also may provide an audio message based on the output or convey the output to user 1002 a in another known way. Other personal devices with displays may also receive outputs from processor 1030, including laptop computers, tablets, mobile phones, glasses, and clothing.

Once user 1002 a receives an output from processor 1030 via his personal device, he may acknowledge receipt of the message related to the output, which may in turn be conveyed to organizational user 1002 j via processor 1030.

In various embodiments, processor 1030 may also generate an output specifically for organizational user 1002 j (an organizational output) and may include various information. For example an organizational output or outputs may include information regarding a user's or users' acknowledgement receipts, the number of outputs sent to users, which users, teams, or groups received outputs, the types of rewards suggested in the outputs, how users reacted to encouragement or motivation, user preferences or interests, user behavior, other information, or any combination of the above. Based on additional data from sensor 1010 collected after a user receives his reward, the organizational output may also include information on whether the user accepted any offered rewards or engaged in any encourage behaviors. for example, the organizational output may include information on whether user 1002 a exited chair 1014 when system 1000 suggested he stand up after a prolonged period of sitting. As discussed in conjunction with FIG. 43, in certain embodiments, the type of data provided in an organizational output may be limited by the nature and potential sensitivity of the information.

FIG. 45 illustrates a method 1100 of providing information to a user of an article of furniture, similar to systems 600, 700, 800, 900, and 1000 discussed above. In particular embodiments, method 1100 is directed toward providing encouragement, motivation, coaching, or a reward to a user. Method 1100 begins at step 1110 by sensing a data set about a user. In various embodiments, this sensing occurs through a sensor coupled to an article of furniture, such as a chair or table. Sensors capable of sensing a data set about the user could alternatively or additionally be positioned on a partition, wall, cabinet, shelving, ceiling, windows, doors, flooring, or on or from another surface within the work environment. In some embodiments, multiple sensors within the environment will sense data about a user; some sensors may have different sensing capabilities than others or sensors may be selectively utilized to sense certain characteristics. Sensors may sense changes in temperature, pressure, light, sound, movement, or other characteristics associated with a user's interaction with the work environment. Data sensed by the sensor constitute the data set. In some circumstances, the data set may be limited to a single sensed data point. In other embodiments, the data set includes a number of data points and may include all or some of the measurements taken by the sensor.

Sending the data set to a processor continues method 1100 in step 1120. In some embodiments, the processor may be similar to processors described previously in conjunction with FIGS. 1 through 5. The processor may receive data directly from the sensor or indirectly through an intermediate device such as a gateway. In certain embodiments, the processor may only receive a single data set as described in conjunction with step 1110. And in some embodiments, the processor may receive multiple data sets from a particular sensor, single data sets from a group of sensors, and/or multiple data sets from a group of sensors. The processor may aggregate, store, sort, analyze, and otherwise process the data upon receipt.

Step 1130 includes generating an output based on the data set and an input from an organizational user. In particular embodiments, the processor may solicit an input from the organizational user upon receiving a data set or data sets, at a pre-determined time, or based on some event, such as input from a user. The processor may have received the input from the organizational user at approximately the same time as it received the data set from the sensor or at an earlier or later time. In some embodiments, the organizational user may provide input upon initializing a system like system 1000, at regular intervals, at irregular intervals, or at any beneficial time. For example, an organizational user may manually or automatically provide input to the processor once a day. In various embodiments, the input provided by the organizational user may depend on additional factors or data sets, including one or more calendars, meteorological information, financial metrics, or group or individual user preferences. Input from the organizational user may provide direction on the type of output appropriate for a group of users, type of user, or individual user. Generated outputs may include a variety of different information, including information designed to motivate, encourage, reward, or otherwise influence the user. For example, the output may be designed to motivate the worker in some way. As described above, worker wellbeing may increase when a worker is able to mindfully engage in his or her work; a related output might encourage the worker to stay focused or to take a break in order to improve focus later. The output may be designed to encourage the worker. Worker wellbeing may increase when a worker knows his or her work is meaningful to the organization; a related output might encourage the worker by providing recognition of his or her effort on a current task. Worker wellbeing may also increase when a worker vitality is encouraged; a related output may reward a worker for prolonged attention (as measured by occupancy in a chair, by stillness in a chair, or by other sensor measurements) over an morning, afternoon, week, month, or other time period by suggesting the user take a break to change postures, to take some time away from the project, or to change his or her routine.

In some embodiments, the output may be provided for a group or groups of users, but not for a particular user. In these embodiments, the system will generate the output based on at least the data set it receives from the sensor and the input from the organizational user. For example, the sensor may indicate that a user has been sitting in his chair for over two hours and the input may instruct the system to provide an output to users sitting for over two hours where the output encourages the user to change posture and stand up. In other embodiments, the output may be provided for a particular user and in these embodiments the system may generate an output that may also be based on a specific user's preferences, for example a personal enjoyment of a particular beverage like coffee or even a particular coffee drink such as cappuccino. In this example, the sensor may indicate that a user has been sitting in her chair for over two hours. The input associated with the user may instruct the system to provide to users who have been sitting for over two hours and who have input a personal preference regarding a beverage an output regarding a break. As a result, the user may receive an output encouraging the user to take a break and enjoy a cappuccino. The user may perceive this as encouragement that helps the user stay focused if the user pays for the cappuccino and may perceive it as a reward for the user's efforts if the user receives the beverage complimentarily.

Method 1100 concludes with step 1140 by sending the output to the user. Method 1100 may include a variety of additional or alternative steps. For example, in certain embodiments, the output may be displayed as a message based on the output via an application on a personal device of the user. Personal devices may include laptop computers, tablet computers, wearables, such as glasses, watches, and clothing, or other devices suitable for a work environment. A user's personal device may also convey the output to the user in a way or ways perceptible to the user's other senses, for example, by providing an audio or haptic signal. The method may also include acknowledging receipt of the message or signal and sending the acknowledgment to the processor and/or to the organizational user.

In particular embodiments, the method may include generating an output for the organizational user (an organizational output) and sending it to the organizational user. The organizational output may or may not be related to the output sent to the user. For example, in some embodiments, the organizational output may include aggregated information about the number of users receiving outputs from the system and/or information about the types of outputs received by the users. In certain embodiments, the organizational output may include information regarding the output sent to a particular user and whether the user took any action in response to the output. The method may also in some embodiments include generating an additional data set about the user through input from the user, where the input relates to the original data set generated by the sensor as described in conjunction with step 1110. Using information input by the user may allow the system to take into account user preferences.

A related method may include setting up a system to collect information and provide feedback as described in method 1100, for example, by identifying a selected position for a sensor within a work environment that is appropriate to sense a data set about a user of an article of furniture within the work environment; placing the sensor in the selected position; ensuring the sensor is configured to send the data set to a processor; ensuring the processor is configured to receive the data set from the sensor and an input from an organizational user; to generate an output based on the first data set and the input from the organizational user; and to send the output to the user. An additional related method may include creating a system to collect information about and/or provide information to a group of users by providing a plurality or group of furniture in a work environment; providing a plurality or group of sensors that are positioned within the work environment and are configured to sense individual data sets about the group of users of the furniture; and providing a processor configured to receive the individual data sets from the plurality of sensors; to receive an input from an organizational user; to generate a plurality of outputs based on the individual data sets and the input from the organizational user; and to send one or more outputs to one or more users.

FIG. 46 illustrates a system 1200 for providing information to a user of an article of furniture, similar to systems 600 through 1000 described above. System 1200 provides information to a user or users at a time or within a time range that may improve the user's overall productivity. For example, system 1200 may generate an output for a user that the system holds until a time more appropriate for interruption.

System 1200 includes user 1202 a, displays 1204 a and 1204 b, sensors 1210, chair 1214, table 1216, gateways 1220, and processor 1230. Any number of users, displays, sensors, furniture, gateways, processors, and other components may be included in various embodiments.

User 1202 a is affiliated with an organization and is associated with chair 1214, table 1216, and displays 1204 a and 1204 b. In the illustrated embodiment, display 1204 a is included in a tablet and display 1204 b is included in a mobile telephone. In some embodiments, display 1204 a or 1204 b may be included in a variety of devices, such as desktop or laptop computers, tablet computers, personal phones, or other wearable devices. Displays 1204 a or 1204 b may be included in a variety of environmental locations, including walls, partitions, ceilings, windows, floors, desks, chairs, storage furniture, and other furniture. In some embodiments, user 1202 a may be associated with one display or may be associated with many displays.

Chair 1214 and table 1216 are equipped with sensors 1210. Similar to the sensors described previously in conjunction with FIGS. 39 through 45 and other figures above. Sensors 1210 may sense changes in pressure, temperature, movement, and other environmental changes. Sensors 1210 may also be configured to sense changes in a variety of health indicators, including blood pressure, breathing rates, heart rates, blood glucose levels, brain function, and other indicators. In some embodiments, sensors 1210 may sense information correlated to a user's identity, such as a name or an employee number, by sensing the presence of the user's badge or a personal device associated with the user. In embodiments where multiple sensors 1210 sense information correlated to a user's identity, it may be possible to estimate the location of the user through, for example, triangulation.

Information collected by sensor 1210 may be useful to user 1202 a and may include information regarding user 1202 a's posture, the length of time user 1202 a has been sitting or standing, the likelihood that user 1202 a might benefit from a change in location or activity, and/or the current status of various health indicators. As described with respect to sensor 810 and chair 814, in some embodiments chair 1214 may include a greater or fewer number of sensors and these sensors may be positioned anywhere on chair 1214. For example, sensors may be embedded in or coupled to a seat, back, headrest, arms, pedestal, base, or casters.

As sensors 1210 collect data about user 1202 a, sensors 1210 transmit some or all of the data to processor 1230 via gateway 1220. Processor 1230 processes the data it receives from sensors 1210. Processor 1230 may also receive and process additional data from user 1202 a or from other sources. Processor 1230 may include several processors depending on the embodiments and these and/or other determinations may be made by the system at various processors.

In the illustrated embodiment, processor 1230 generates one or more outputs about a user or for the user based on available data. As discussed in conjunction with similar systems 600 through 1000, the generated outputs may include a variety of information and communications. For example, processor 1230 may determine, based on the data received about user 1202 a, that user 1202 a should change posture, location, or task. In certain embodiments, data associated with user 1202 a may reflect a change in a health indicator, such as a change in breathing rate, and processor 1230 may determine that user 1202 a should shift to a different activity. Processor 1230 may configure these determinations about user 1202 a as one or more outputs for communication to user 1202 a that encourage user 1202 a to act in accordance with the suggested change.

In the illustrated embodiment, processor 1230 additionally determines when to communicate the output to user 1202 a. Processor 1230 may rely on a number of factors and data sources in determining a preferred time for communication. As described herein, a preferred time for communication may be a particular time or may be a window or range of time, for example, a several minute range of time before, after, or encompassing a particular time.

Processor 1230 may determine a preferred time according to affirmative feedback from user 1202 a, such as information solicited or received from user 1202 a regarding user 1202 a's desire to only be interrupted with outputs from system 1200 at certain time intervals or in conjunction with the ending or beginning of various calendar entries. Processor 1230 may determine a preferred time according to historical, sensed feedback from user 1202 a, such as data collected over a period of time showing that user 1202 a tends to begin shifting more in a chair, possibly indicating a reduction in focus, after a certain length of time; processor 1230 may determine the preferred time for communication in conjunction with the anticipated time that user 1202 a's focus and attention to his current task is changing. Processor 1230 may also determine the preferred time according to real-time, sensed feedback from user 1202 a, such as data showing that user 1202 a was sitting still and has begun to shift and move within a chair, possibly indicating a change in focus; processor 1230 may determine that the preferred time for communication is the time when user 1202 a's movement data changes.

A preferred time for communication in some embodiments may be determined by processor 1230 directly in conjunction with various calendar entries. For example, processor 1230 may receive information that user 1202 a is scheduled to attend a meeting at some time in the future; processor 1230 may determine a preferred time for communication is a certain amount of time before the meeting starts, is near the meeting start time, or is near the meeting end time. In addition, processor 1230 may tailor the output in light of various calendar entries. For example, processor 1230 may determine that user 1202 a has been sitting for most of the morning and should spend at least some time standing to complete assigned tasks. The output may take calendar entries into account, and may suggest or encourage user 1202 a to stand during the meeting or to stand after the meeting.

In various embodiments, processor 1230 determines a preferred time for communication in accordance with user 1202 a's usage of electronic applications. In the illustrated example, user 1202 a uses tablet with display 1204 a. As user 1202 a works on a selected task, user 1202 a utilizes a particular application on the tablet. Processor 1230 may determine that a preferred time for communication is when user 1202 a switches from the particular application to a second application, which may be correlated with a task change or may reflect that user 1202 a is ready for a break. For example, processor 1230 may determine that user 1202 a is working on a particular task based on his selected application, processor 1230 may then determine that user 1202 a has completed the task or a portion of the task, because user 1202 a is switching from the selected application to a different application, and processor 1230 may then determine that the preferred time for communication is approximately when user 1202 a switches from the first to second application. Similarly, processor 1230 may determine that a preferred time for communication is when user 1202 a switches between personal devices, for example, switching between an application viewable on tablet display 1204 a to an application viewable on mobile display 1204 b.

Processor 1230 sends the output to user 1202 a at or near the preferred time for communication. Any number of factors, data sets, and inputs from user 1202 a, from user 1202 a's environment, or from user 1202 a's employer may be used in determining the preferred time for communication. The benefits of waiting to communicate with user 1202 a until at or near a preferred communication time include allowing user 1202 a to maintain engagement with and/or concentration on a present task.

In some embodiments, processor 1230 may send some outputs directly to user 1202 a without delay. Direct outputs to user 1202 a may occur when the output is of a particular nature, for example, a change in a critical health indicator such as blood glucose, or a change exceeding a certain magnitude, such as a change in heart rate exceeding a pre-set limit. In some embodiments, the timing of the output to user 1202 a may depend on the magnitude of the associated information. For example, it' a change in heart rate is below a certain threshold, processor 1230 may send a related output to user 1202 a only at a preferred time, however if the change in heart rate is above a certain threshold, processor 1230 may send the related output to user 1202 a without delay. Outputs based on significant changes, such as changes in critical health indicators, may additionally be sent to other users, including users in close physical proximity and/or certain organizational users, such as a user in human resources, security, or in a management role.

Similar to systems 600, 800, and 1000, described above, outputs received by user 1202 a may be displayed on a personal device, including for example on display 1204 a on user 1202 a's tablet and/or display 1204 b on user 1202 a's phone. Further similar to system 800, system 1200 may send an output to an organizational user based on the data set associated with user 1202 a. In some embodiments, data sets of a group of users including user 1202 a may be aggregated or otherwise analyzed by processor 1202 a and an output regarding the group may be sent to an organizational user. Information that may be sent to an organizational user may include information about the current location of user 1202 a and/or other users of system 1200. Information regarding the length of time user 1202 a and/or other users have remained in one location may also or alternately be included. In certain embodiments, additional information may also flow from an organizational user to user 1202 a. For example, an organizational user may provide additional outputs for user 1202 a that are sent to user 1202 a at a preferred time determined by system 1200. This may allow an organization to push information to users without disrupting users at inopportune times.

Users typically desire to engage fully in their tasks and employers similarly want users to be able to engage mindfully in selected tasks without interruption. System 1200 allows users to receive beneficial information generated for the users that is delivered at an appropriate time or within an appropriate time range, which may improve the distribution of information without reducing productivity.

FIG. 47 illustrates a method 1300 of providing information to a user of an article of furniture through a system, similar to systems 600 through 1200 discussed above. Method 1300 is directed toward creating a system that can provide information to a user at an appropriate or preferred time. In certain embodiments, the steps disclosed in method 1300 allow the system to prepare information for a user, hold or retain it, and then send it at a preferred time that may not cause an unwanted interruption in the user's work. For example, a user may want information about the location of his team or a reminder to stretch his legs, and he may prefer to receive that information as he switches between tasks, between meetings, or after he's enjoyed a period of time in which he can concentrate on his work. Method 1300 enables a user or users to receive the benefits from participating with the system without sacrificing benefits associated with concentration or from being in the “flow,” i.e., in a state where productivity and focus are high.

Step 1310 begins method 1300 by sensing a data set about a user of an article of furniture. Sensors capable of sensing data about a user may be coupled to a variety of articles in the user's environment, including, for example, chairs, tables, floors, storage cabinets, partitions, walls, displays, ceilings, and floors. Sensors may sense changes in temperature, pressure, light, or sound and may include information on the user's presence, activity level, and/or movement. Sensed data may also include one or more indicators of a user's health or wellbeing, such as temperature, heart rate, blood glucose levels, breathing rate, blood pressure, body mass index, and/or brain activity. Within a user's environment, only one sensor, for example, a sensor coupled to the user's chair, may be sensing information about the user. In other embodiments, multiple sensors may be sensing information about the user; these sensors may each be sensing the same type or types of data or particular sensors may be sensing specific information about the user. Sensors for sensing data about the user may be placed within the user's environment depending on the type of information that a user or organization hopes to sense. For example, a sensor coupled to a user's chair may sense information about the user's movement within the chair, from which information on a status of or a change in the user's concentration may be derived. In some embodiments, a sensor positioned in the environment, for example, coupled to a partition or wall, may be able to sense information about a user's presence within the environment, even if he isn't in physical contact with any of the furniture or articles in the environment, while. Various sensors may sense information on a user's identity. Data sensed by the sensor constitute a data set and may include one or more data points.

Method 1300 continues with step 1320 by sending the data set to a processor. The processor may be similar to processors described previously in conjunction with FIGS. 1 through 7. Although referenced in the singular herein, a processor may comprise several processors that may be located together or remotely from one or more other processors and/or components of the system. Data sent to and received by the processor may be received directly from a sensor or may be received through one or more intermediaries, including for example a gateway, similar to gateway 1220. The processor may receive data from a single sensor, multiple sensors associated with a particular user, or multiple sensors associated with multiple users. The processor may also receive other data about users of the system. The processor may aggregate, store, sort, analyze, and otherwise process some or all of the data upon receipt.

Step 1330 includes generating an output based on the data set. Similar to steps 930 and 1130 described in conjunction with methods 900 and 1100, respectively, the processor generates an output based on some or all of the data received. As noted in conjunction with step 1320, in certain embodiments, the processor may access additional sources of information contained within the system and the output may be based on the data set and additional data sources. For example, the processor may receive information from a sensor associated with a user and a sensor tracking ambient noise levels in a space associated with the user. The processor may analyze the data and determine that the user moves in his chair around the same time that an audible interruption occurs, which may indicate that the audio interruption is reducing the user's ability to focus on his current task. The processor may have access to additional information including current task information from the user and scheduling information for nearby environmental resources, such as shared workstations or conference rooms. The processor may generate an output for the user, suggesting that he move to a workstation that is not subject to audible interruptions. Other exemplary outputs may include encouragement for a user to change posture after receiving sensed data indicating the user has been in a similar position for a period of time; a suggestion for an available work environment; communication including motivation, encouragement, or rewards; communication regarding the status of one or more health indicators; information regarding a user's schedule or upcoming calendar commitments; task-specific information; communication about the proximity of another worker or workers; and/or environmental information, such as ambient noise, light, and temperature information.

Step 1340 continues method 1300 by determining a preferred time for communication with the user. The preferred time for communication may be determined in various ways and may be a particular preferred time or a preferred range of time. For example, the preferred time for communication may be determined in conjunction with feedback from the user regarding the user's preferred time and manner of communication. In certain embodiments, the system may solicit feedback directly from the user via an application on a personal device. For example, the system may inquire what type of feedback the user prefers, how often the user takes breaks to optimize output, what types of working environments are most conducive to productive work generally or for specific tasks, and/or other inquiries related to the user's preferred environment to improve productivity. In some embodiments, the system may exclusively rely on affirmative responses to determine a preferred time. It may also rely partially or fully on sensed data about the user. For example, the system may determine a preferred time for communication by sensing and correlating information about when a user choose to act or not act on suggestions contained in the system's outputs with the times at which the user received these outputs.

In various embodiments, a preferred time may be set and not variable; for example, it may be related to a particular time interval or particular time of day. A preferred time for communication may also be dynamic and depend on one or more factors. As noted previously, the system processor may receive or have access to other sources of information about a user and/or environment and this information may impact the determination of a preferred time. For example, processor may access information about a user's current task and may determine that a preferred time for communication is immediate (e.g., if the task is not time sensitive) or is in the future (e.g., at the completion of the task or if the task is time sensitive and/or is incomplete). In particular embodiments, the processor may access information about a user's device usage or devices associated with the user. For example, the processor may access information about devices associated with a user and may determine that the preferred time for communication is approximately the time when the user switches from one device to another (e.g., when a user stops working on a computer or tablet and checks a message on a phone). The processor may alternately or additionally access information about application usage on a user's device and may determine that a preferred time for communication is approximately the time when a user switches from one application to another (e.g., when the user switches from a document creation application to an email application) or between views in an application (e.g., when the user switches from one browser tab to another). The processor may also access, in certain embodiments, information associated with a user's calendaring or scheduling application and may determine that a preferred time for communication is at a time that corresponds approximately to an entry in the calendaring application (e.g., just before a user would stop or interrupt a task to attend a video conference or in-person discussion).

In some embodiments, the processor may determine that a preferred time for communication is when the user begins to lose focus on a current task. The processor will then continuously or regularly analyze the sensed data it receives regarding the user. When the processor determines from the sensed data that the user may be losing focus, the preferred time for communication will have arrived. This may occur, for example, when the sensed data shows that the user is working on a task and sitting relatively still in a chair, and then, while continuing to complete the task, the user increasingly begins to shift in the chair. A preferred time for communication or way the processor determines a preferred time for communication may also be established by someone other than the impacted user, including for example, by an organizational user. For example, in some embodiments, windows of time for communication may be set by an organizational user and the system may rely on sensed data of a user to determine a preferred time for communication with the user within the window set by the organizational user.

Method 1300 concludes with step 1350 by sending the output to the user at approximately the preferred time for communication. By sending the output to the user at the preferred time for communication, a user may benefit from the information conveyed by the system without incurring an additional interruption. By controlling the timing of any communications, workers may be more interested and/or willing to become users of the system. Unmanaged interruptions may reduce work productivity. Consequently, managing the timing of interruptions, by determining a preferred time for communication, may allow one or more users to engage more productively in work and may avoid or reduce the decrease in productivity often attributed to workplace interruptions.

Method 1300 may include several additional or alternative steps. For example, outputs may be displayed to a user via an application on a device associated with the user. The application may be an application specific to the system or an application used for other functions, such as a web browser. In some embodiments, an output may be sent to one or more users, for example, multiple users may be notified that their teammates are located in a given area. An output may also be sent to an organizational user; this output, similar to the organizational outputs described previously, may include information about a user or group of users. Additional variations on method 1300 or related methods may include a method for setting up a system to collect information about one or more furniture users by identifying or selecting a position within a work environment that is appropriate to sense a data set about a user of an article of furniture within the work environment, placing a sensor in the selected position, and ensuring the sensor can send the data set to a processor, where the processor is configured to generate an output based on the data set, determine a preferred time range for communication with the user, and send the output to the user during the preferred time range for communication. In some embodiments of this related method, the sensor may be coupled to the article of furniture, such as a chair. Another related method may include creating a system for collecting information about a plurality of users in a particular environment, such as a work or office environment, and may include providing a plurality of articles of furniture in a work environment, providing a plurality of sensors positioned within the work environment that are configured to sense individual data sets about a plurality of users of the articles of furniture, and providing a processor configured to receive the individual data sets from the plurality of sensors, determine a preferred time range for communication with one or more users of the plurality of users, and send the one or more outputs to the one or more users during the preferred time range for communication. Similarly, in this related method, each of the sensors may be coupled to one of the plurality of articles of furniture, which may be a grouping of chairs.

FIG. 48 illustrates system 1400 for providing information to a user of an article of furniture, similar to systems described above in conjunction with FIGS. 39 through 47. System 1400 provides information that may help users better collaborate with the users' colleagues. For example, in certain embodiments, system 1400 may sense that two users are working on similar tasks and may send information to one or both users about a space they could use to work together.

System 1400 includes users 1402 a, 1402 c, and 1402 j, displays 1404 a, 1404 c, and 1404 j, sensors 1410, chairs 1414 a, 1414 b, 1414 c, 1414 d, 1414 e, and 1414 j, tables 1416 a, 1416 b, 1416 c and 1416 j, gateway 1420, and processor 1430. Any number of users, displays, sensors, furniture, gateways, processors, and other components may be included in various embodiments.

Users 1402 a and 1402 c are affiliated with an organization and may have a variety of responsibilities. They may be assigned to work on the same team for all or some tasks, or may have no overlapping or coordinating activities. Users 1402 a and 1402 c may or may not know each other. User 1402 j is also affiliated with the organization and has organizational responsibilities. Although user 1402 j is illustrated here as one person, in various embodiments, organizational user 1402 j may include any suitable number of people or computers with organizational responsibilities.

In the illustrated embodiment, user 1402 a is working at a work station that includes chair 1414 a and 1416 a. A nearby workstation includes chair 1414 b and table 1416 b. User 1402 c is working at a work station that includes chair 1414 c and table 1416 c. User 1402 j is working at a work station that includes chair 1414 j and table 1416 j. Chairs 1414 d and 1414 e are located near each other and remote from the work stations described above.

Each of the chairs 1414 and tables 1416 are equipped with sensors 1410. In the illustrated embodiment, sensors 1410 are configured to collect data or sense information about users 1404. Sensors 1410 coupled to chair 1414 a and table 1416 a collect data about user 1404 a; sensors 1410 coupled to chair 1414 c and table 1416 c collect data about user 1404 c; and sensors 1410 coupled to chair 1414 j and table 1416 j collect data about user 1404 j. Sensors coupled to chairs 1414 b, 1414 d, 1414 e and tables 1416 b, 1416 d, 1416 e may collect information as well, which may primary consist of information about the lack of any user activity. Similar to the sensors described previously in conjunction with FIGS. 1 through 8, sensors 1410 may sense changes in pressure, temperature, movement, and health indicators. Information collected by sensors 1410 may be correlated to a user's presence near one or more sensors 1410. a user's posture, a user's focus or mental engagement, and/or a user's health and wellbeing. Additional sensors may be present in the described work environments in a variety of locations.

Sensors 1410 are configured to transmit some or all of the sensed data to processor 1430 via gateway 1420. Processor 1430 processes the data it receives from sensors 1410. Processor 1430 also has access to information regarding the organization, which it receives in sum or in part from organizational user 1402 j. Information regarding the organization may include information about users, such as users 1402 a's and 1402 c's assigned tasks, colleague identities, team member identities, or supervisor identities, as well as information about environmental resources, such as meeting rooms, project rooms, project resources, prototyping resources, videoconferencing resources, and nourishment locations. Processor 1430 may also receive or have access to additional information related to users 1402, including for example, current application usage on any personal devices, calendars, email patterns and traffic, and personal preferences.

In the illustrated embodiment, processor 1430 generates an output or outputs based on the data it receives, including data about users 1402 a and 1402 c from sensors 1410 and data regarding the organization from organization user 1402 j. Outputs include information about another user's location or activity, information about environmental locations conducive to collaboration, independent work, or down-time, and/or information about productive changes in upcoming calendar events or additional calendar events. A variety of outputs are available based on the sensed data received by processor 1430.

In certain embodiments, after receiving sensed data about users 1402 a and 1402 c regarding their respective and separate locations and receiving information from organizational user 1402 j that users 1402 a and 1402 c are working together on a project, processor 1430 may generate an output with location information about one or both users. For example, the output may direct user 1402 a that a colleague, such as user 1402 c, is working in a nearby location, identify the location, and/or provide directions or travel time to the location. In particular embodiments, processor 1430 may generate an output with varied location information about multiple colleagues or multiple teams.

Processor 1430 may additionally or alternatively receive information about the present tasks of users 1402 a and 1402 c. Processor 1430 may generate an output for user 1402 a regarding the activity of user 1402 c. For example, an output generated for user 1402 a may include information that user 1402 c is working on a similar task, is working on a task that is on user 1402 a's agenda but has not yet been started, or is completing a task for which both users 1402 a and 1402 c share responsibility. Processor 1430 may also generate an output for user 1402 a with information about the location of a group of users who have been assigned the same or similar task and the current status of the group members' work.

In some embodiments, generated outputs may include task and location information. For example, the output may include information for user 1402 a that a colleague, such as 1402 c, is working on a similar task at a nearby location and may identify the location. These outputs may allow users of system 1400 to better collaborate with teammates, especially when teammates are mobile workers or are working in distributed locations. Similar outputs regarding task and location may allow users more accurately to find assistance for a given task. For example, organizational user 1402 j may provide information to processor 1430 regarding the experiences or expertise of a given group of users. Processor 1430 may then generate an output for user 1402 a with information about the location of a system user who has had previous experience in a type of task, should user 1402 a need assistance.

In certain embodiments, processor 1430 may generate an output with location information for a user or group of users regarding a location for collaboration. For example, processor 1430 may receive sensed data indicating that user 1402 a and user 1402 c are present but in separate locations. Processor 1430 may also receive sensed data indicating that chairs 1414 b, 1414 d and 1414 e are vacant and available. Based on this sensed data and an input from organizational user 1402 j, processor may generate an output that suggests that user 1402 c move closer to user 1402 a by occupying chair 1414 b, or that users 1402 a and 1402 c may be able to collaborate or work together at chairs 1414 d and 1414 e. Processor may rely on other information, including for example, ambient noise, task, distance from each user, user preferences, and/or other factors, to determine which option to suggest. The outputs may include the locations of chair 1414 b or chairs 1414 d and 1414 e, respectively. In various embodiments, a suggested location for collaboration may include certain chairs, tables, lounge spaces, nourishment spaces, meeting spaces, spaces with videoconferencing capabilities, confidential spaces, or development spaces, and may depend on a variety of factors, including the number of participating users, the tasks of the users, the identity of the users, and the present location of the users.

Processor 1430 sends one or more of the generated outputs to one or more users of system 1400. In several of the examples described above, processor 1430 sends the output to at least user 1402 a. Outputs may also be sent to user 1402 c, organizational user 1402 j, and other users or groups of users. Outputs sent to a user or users may be displayed on a personal device of the user, including for example, a mobile phone, a tablet, a laptop computer, or other display affiliated with the user. The output or a communication based on the output may be displayed on the personal device of a user via an application related to or developed Cor system 1400 or via an application that may be used for many purposes, such as a web browser.

Benefits of system 1400 may include the ability of individual users to identity and/or locate team members more efficiently, which may allow a mobile workforce to collaborate more easily. In some embodiments, additional benefits of system 1400 may include increased productivity for users, for example, in situations where a user needs help completing a task and receives information on the location of a user who can provide assistance.

FIG. 49 illustrates a method 1500 of providing information to a user of an article of furniture through a system, similar to systems 600 through 1400 discussed above. Method 1500 is directed toward generating and sharing providing information on the locations and activities of system users in order to foster collaboration. Method 1500 allows a user to receive information regarding the location and activities of his colleagues. Method 1500 may be particularly helpful in work environments where some or all workers are mobile or are not assigned a particular workstation for day-to-day tasks. Information on the location and/or activities of other users, may allow a user to find or contact others on his team for collaboration. Method 1500 may also be helpful in work environments where multiple users, who would benefit from working together to complete a task, select or are assigned to remote workstations. By receiving information about the location and/or activity of other users, a user can make an informed decision as to whether moving to another location might help accomplish a given task.

Method 1500 starts with step 1510 by sensing a first data set about a first user and proceeds to step 1520 by sensing a second data set about a second user. Steps 1510 and 1520 occur via one or more sensors present in the work environments of the first and second users. A sensor configured to sense a first data set or a second data set may be coupled to or embedded in an article of furniture, such as a chair, desk, lounge furniture, or storage furniture, or to or in structural elements within the environment, such as partitions. walls. ceilings, or flooring elements. Each data set may include one or more pieces of data. In some embodiments, a data set will include all data points sensed or collected by one or more sensors or may include only some of the data points sensed by one or more sensors.

Method 1500 continues by sending the first and second data sets to a processor. The sensors described in conjunction with steps 1510 and 1520 will transmit data to a processor. Sensors may send data continuously, sporadically, at regularly timed intervals, or whenever data is generated. One sensor with the system may send data at different times than some or all other sensors within the system. In particular embodiments, sensors will receive a notification prompting the transfer of some or all sensed data. The processor may be a single processor or a collection of processors, which may be physically located near or remotely from one or more work environments including sensors. Some or all sensors may, in certain embodiments, transmit data to the processor through an intermediary device, such as a gateway. In addition to the first and second data sets, the processor may have access to or may receive additional data. For example, the processor may receive information about some or all users of the system, including information on user roles within the organizational structure; user positions, tasks, and activities; calendaring information; and information about the personal devices of users. This additional information may, in some embodiments, be received directly or indirectly from a user within the system who has responsibilities for managing the organization, often described herein as an organization user.

In embodiments where one or more sensors are positioned within a space assigned to an individual user, any data collected by the sensor or sensors may be attributed by the processor to the individual user based on the sensor identity. In embodiments where sensors are positioned within a space that accommodates mobile users or a group of users, the processor may not be able to assign data automatically to a certain user or users. In these embodiments, the processor may utilize an alternative correlation between sensed data with a particular user in order to provide feedback to that user. For example, one or more sensors within the system may be able to sense and collect data about an aspect of the user's activity (e.g., the user's movement) and collect data about the user's identity. Sensors may be able to collect information about the user's identity by sensing and identifying a user's badge or personal electronic device such as a phone, wearable, tablet, or laptop. Approximate user location may be determined by identifying the location of one or more sensors that are collecting data about a user. Multiple sensors may be able to triangulate a user's location. Sensors may transmit user identification data separately or with other data and identification data may be a part of the first and/or second data sets disclosed in steps 1510 and 1520.

Step 1540 continues method 1500 by generating an output based on the first and second data sets and an input from the organizational user. As described above in conjunction with step 1530, processor may access additional information about a user or an environment. This additional information may be accessible in whole or in part via one or more inputs from an organizational user. For example, a user with some responsibilities for running an organization may provide information to the system regarding tasks and teams of various users. The processor is then able to use the sensed data collected in steps 1510 and 1520 and the organizational input to generate an output. The output may include information about a user's tasks, teammates, or current or suggested work environment.

For example, the processor may receive sensor information indicating that two users of the system are present within a given proximity of each other. The processor may also receive or have received information from an organizational user that the two users are both tasked with working on a project. Upon receiving information about the users, the processor may generate an output for one user that includes information on the location of the other user. This may allow one user to seek out the other user for assistance or to collaborate in person. Alternately, in embodiments where the users may or may not be present within a given proximity of each other, the processor may generate an output for one or both users that includes information on their respective locations and information on a possible physical meeting location or on a method to meet and discuss electronically, for example, information on a video conferencing site for one or both users.

After receiving the information described above, the processor may generate additional or alternate outputs. Examples include an output with information on the location of a manager or supervisor, information on the progress of a colleague or teammate on a task, or information on available work environments.

Method 1500 concludes at step 1550 by sending the output to the first user. In various embodiments, method 1500 will include different or additional steps. For example, in some embodiments, sending the output to the first user will include displaying the output via an application on a personal device of the user. An output that is the same, similar, or different may be sent to one or more other users, including an organizational user, groups of users, or all users. A variation on method 1500 may creating a system to provide similar information to users by identifying a plurality of positions within a work environment appropriate for sensing, placing a first sensor in a first position of the plurality of positions, where the first position is appropriate to sense a first data set about a first user of a first article of furniture; placing a second sensor in a second position of the plurality of positions. where the second position is appropriate to sense a second data set about a second user of a second article of furniture; and ensuring the first and second sensors are configured to send the first and second data sets to a processor, where the processor is configured to generate an output based on the first and second data sets and an input from an organizational user and to send the output to the first user. Another variation on method 1500 may include creating a system for collecting information about a group of users by providing a plurality of articles of furniture in a work environment, providing a plurality of sensors in the work environment that are configured to sense individual data sets about a plurality of users of an article of furniture; and providing a processor configured to receive the individual data sets from the plurality of sensors, to generate one or more outputs based on the data sets and one or more inputs from an organizational user, and to send the one or more outputs to the one or more users. In some embodiments, one or more of the sensors may be coupled to the articles of furniture, which may often be office chairs.

The technical benefits of these method steps may include allowing a group of users to connect more efficiently with colleagues, teammates, and mentors. Several of these steps may allow a distributed team or mobile work force to collaborate more easily, which may increase productivity and user satisfaction.

The chair assembly 10 can include a one-point heating element arrangement in each arm assembly 20, with a full length heating element 1628 for heating a user's elbows, forearms, and wrists, a rear heating element 1630 for heating a user's elbows, or a front heating element 1632 for heating a user's forearms and/or wrists. The chair assembly 10 can include a two-point heating element arrangement in each arm assembly 20, with the rear heating element 1630 and the front heating element 1632.

Referring to FIG. 50, the chair assembly 10 can utilize a heat application mapping module 1614 in the back assembly 18, such as a smart fabric that can selectively apply heat to any of the locations described herein with respect to the back assembly 18. Referring to FIGS. 50 and 51, the chair assembly 10 can utilize a heat application mapping module 1624 in the seat assembly 16, such as a smart fabric that can selectively apply heat to any of the locations described herein with respect to the seat assembly 16. Referring to FIG. 51, the chair assembly 10 can utilize a heat application mapping module 1634 in the arm assemblies 20, such as a smart fabric that can selectively apply heat to any of the locations desired herein with respect to the arm assemblies 20.

The chair assembly 10 can include any combination of the heating element arrangements for the back assembly 18, the seat assembly 16, and the arm assemblies 20. In some aspects, the chair assembly can include all or some of the heating elements described herein and a user must activate the heating elements in a commissioning process.

The heating elements shown in FIGS. 50 and 51 are of an exemplary size and shape and can be bigger, smaller, or shaped differently than pictured. The heating elements shown in FIGS. 50 and 51 are positioned in exemplary locations and in certain aspects, the positions are customizable to a particular user. For example, the upper elements 1604 can be positioned higher for a person with a longer torso or lower for a person with a shorter torso.

The heating elements can be manually repositioned by a user in at least some embodiments. For example, the back assembly 18 could contain a plurality of foam inserts in various locations where a user might desire a heating element, and the user could replace the foam insert with a heating element in a location that is customized to the user's physical dimensions. Alternatively, the heating elements may be repositioned by a motor mechanism, which can move in response to a specific user command or in automatic response to a user's physical dimensions, which can be programmed or sensed by the chair assembly. In the event the best available medical knowledge changes, the heating elements described herein may be deployed in a variety of additional locations, so as to be suitable for applying heat to a user according to the best available medical knowledge.

Control of the heating elements may be dynamic in at least some embodiments. To this end, for instance, one or more heating elements may be cycled through different temperatures where the changing temperature is intended to help maintain a chair user's alertness. The cycling may only be controlled for one or a subset of chair heating elements while others are maintained at a constant or steady state temperature. In some cases the heating element temperature or cycling pattern may be adjusted as a function of sensed parameters within the chair seat and/or backrest structure. For instance, where pressure is substantial at one seat location, heat may be applied at a different seat location or at several other seat locations to encourage the employee to shift her weight to what is perceived to be a more healthy position. As another instance, the heat may be cycled on and off at different locations to encourage user movement in cases where that type of activity is perceived to be advantageous. Here, for instance, some employees may shift to avoid applied heat while others shift to encounter applied heat.

Referring to FIG. 52, the chair assembly 10 can utilize a pressure mapping module 1650 in the back assembly 18, such as a smart pressure-sensitive fabric, to generate a pressure map of the user's contact with the back assembly 18 and/or sense any of the relevant pressures described herein with respect to the back assembly 18. Referring to FIGS. 52 and 53, the chair assembly 10 can utilize a pressure mapping module 1660 in the seat assembly 16, such as a smart pressure-sensitive fabric, to generate a pressure map of the user's contact with the seat assembly 16 and/or sense any of the relevant pressures described herein with respect to the seat assembly 16. Referring to FIG. 53, the chair assembly 10 can utilize a pressure mapping module 1668 in the arm assemblies 20, such as a smart pressure-sensitive fabric, to generate a pressure map of the user's contact with the arm assemblies 20 and/or sense any of the relevant pressures described herein with respect to the arm assemblies 20.

The chair assembly 10 can include any combination of the pressure sensor arrangements for the back assembly 18, the seat assembly 16, and the arm assemblies 20. In some aspects, the chair assembly can include all or some of the pressure sensors described herein and a user must activate the pressure sensors in a commissioning process.

The pressure sensors shown in FIGS. 52 and 53 are of an exemplary size and shape and can be bigger, smaller, or shaped differently than pictured. The pressure sensors shown in FIGS. 52 and 53 are positioned in exemplary locations and in certain aspects, the positions are customizable to a particular user. The pressure sensors can be manually repositioned by a user in at least some embodiments. For example, foam inserts can be located in a position where a user might desire a pressure sensor, and the user could replace the foam insert with the pressure sensor in a location customized to the user.

The heating elements can be repositioned by a motor mechanism, which can move in response to a specific user command or in automatic response to a user's physical dimensions, which can be programmed or sensed by the chair assembly 10 in at least some embodiments. In the event the best available scientific knowledge relating to seated posture and health changes, the pressure sensors described herein can be deployed in a variety of additional locations, so as to be suitable for sensing pressure for posture determinations according to the best available scientific knowledge.

In some aspects, the pressure sensors can be used to ensure that there is no or at least minimal pressure in certain locations. For example, referring again to FIG. 52, the seat assembly can include the two front pressure sensors 1658 for sensing if a user's calves are engaged with the front of the seat assembly. According to the currently best available scientific knowledge, the best posture requires space between a user's calves and the front of the seat assembly.

In some aspects, referring to FIGS. 52 and 53, the pressure sensors may be point pressure sensors 1671 that measure essentially a single point of pressure. The point pressure sensors 1671 can be located at positions scientifically determined to be ideal for identifying postures with the minimal number of sensors possible, as shown in FIGS. 52 and 53.

Although there is a general concept of ideal posture according to the best available scientific knowledge, it is generally not ideal for a user to occupy any single posture position for too long, even if it is an ideal posture position. Accordingly, the chair assembly might utilize the pressure sensors to monitor a user's posture to account for the cycling of postures. For example, if it is generally known that there is one ideal posture, and four nearly-ideal postures that are close to ideal but not quite ideal, the chair assembly can monitor pressure sensors or points on a pressure map associated with the one ideal posture and the four nearly-ideal postures when the user initially sits. Then, after sensing that the user is occupying one of these postures and has not moved for a certain length of time, the chair assembly can monitor the pressure sensors or points on a pressure map associated with the other postures that the user is not occupying, in order to prompt the user to occupy one of the other postures, in order to actuate a portion of the chair in order to physically alter the user's posture to conform with one of the other postures, or simply to determine if and when the user moves to one of the other postures.

If the chair assembly senses that a user has occupied a particular posture for a certain period of time, for example, 30 minutes or a length of time considered by the best available medical knowledge to be the longest time a person should occupy one position, then the chair assembly can prompt a user to change postures. The prompt can take the form of a visual or audio cue, a vibration, or an actuation of a part of the chair assembly 10 in an attempt to force the user to occupy a different posture.

In some aspects, the chair assembly 10 can assess posture immediately by taking a “snap shot” of a user's posture. For example, the processor can assess the posture of a user using the snap shot described above, and if the user is sitting with bad posture in the snap shot, then the processor can make a recommendation for an adjustment of posture to the user or can actuate a part of the chair assembly 10 to prompt an adjustment of the user's posture. In some aspects, the chair assembly 10 can assess posture hysteretically by averaging the posture of a user over time. For example, the processor can assess a user's average posture over the course of five minutes, or any other pre-programmed length of time, and if the user's average posture is bad, then the processor can make a recommendation for an adjustment of posture to the user or can actuate a part of the chair assembly 10 to prompt an adjustment of the user's posture.

As the chair assembly attempts to improve a user's posture either by prompting the user to adopt a better posture or by mechanically moving the chair to guide the user's body into a better posture, the improvement can be made slowly over time. For example, the chair assembly 10 may only prompt the user when the user is in a posture that is perceived to be below a certain posture quality level. As another example, the chair assembly 10 may only prompt the user a small number of times per day at first, and then slowly increase the number of times the chair assembly 10 will prompt the user, and eventually, the chair assembly 10 can prompt the user any time the user is not using good posture. As a further example, the chair assembly 10 can slowly adjust the physical position of the chair, the application of heat or vibrations to certain locations of the chair, or a combination thereof in order to adjust the user's posture. This adjustment can be slow enough that it is not easily perceived by the user.

In some aspects, a single component can serve as both a heating element and a pressure sensor, thus allowing application of heat and sensing pressure simultaneously at a single location.

Temperature sensors can measure the temperature of the user, the temperature of a portion of the chair assembly 10 contacted by the user, or an ambient temperature of the environment surrounding the chair assembly 10 and the user. In embodiments where temperature sensors are configured to measure the temperature of the user, they can be located at the same positions as set forth above with respect to the pressure sensors, as shown in FIGS. 52 and 53. In embodiments where a temperature sensor is configured to measure the ambient temperature, the temperature sensor 1682 can be located in a location that the user does not come into contact with, such as on an underside of support assembly 19, as shown in FIG. 55.

As described herein, the chair assembly 10 can include a heart rate sensor. Many of the locations where a pulse can be sensed on a user are inaccessible by a chair supporting a seated user, but some can be accessed by heart rate sensors located in the chair assembly 10. Two different pulses can be sensed in the wrist area, namely, the radial pulse and the ulnar pulse. Referring to FIG. 54, a wrist heart rate sensor 1672 positioned at the front edge of the top surface 55 of one or both of the armrests 53 could measure a heart rate when a user is utilizing the armrests. Another pulse can be sensed in the legs, namely, the popliteal pulse, which can be sensed behind the knee. Referring to FIG. 54, a single knee heart rate sensor 1674 positioned at the front edge of the seat assembly 16 or two separate knee heart rate sensors 1676 positioned at the front edge of a seat assembly 16 where a user's legs are expected to fall could measure a heart rate when a user is sitting appropriately far back in the chair.

As described herein, the chair assembly 10 can include a breath rate sensor. Referring to FIG. 55, the chair assembly 10 can include breath rate sensors 1678 at positions within the back assembly 18 that are proximate the lung cavity of a seated user.

As described herein, the chair assembly 10 can include a galvanic skin response sensor. Because most of the contact points between a user and the back assembly 18 or seat assembly 16 are clothed, the galvanic skin response sensor is preferably located on the top surface 55 of the armrest 53. For example, referring to FIG. 54, the galvanic skin response sensor 1680 can be located in the middle of the top surface 55 of the armrest 53, though other locations on the top surface of the arm assembly 20 are contemplated.

“Flow” is a concept that relates to a mental and physical state where a user is performing in an optimal fashion. Developments have enabled the sensing and detection of a user's flow state. The chair assembly can utilize one or more of the sensors described herein, an on-board processor, and the best scientifically-available techniques for sensing flow, to determine if a user occupying a chair is in a flow state, out of a flow state, entering a flow state, or exiting a flow state. The chair assembly can utilize a visual indicator on the chair assembly, such as one or more LEDs that illuminate in colors representative of an instantaneous or steady state flow state, an optical indicator that projects a certain ambient light about the chair representative of the flow state, a smart material on the chair that changes colors to indicate flow state, etc.

The chair assembly can communicate with other chair assemblies, via a wireless transmitter, and can share data relating to a user's flow state. The visual indicator can then be representative of a user's current flow state relative to other user's, a user's average flow state relative to other user's, the total amount of time a user is in a flow state compared with other users, and the like.

If a processor makes a determination that a user is in a flow state, is being productive, is actively collaborating, or any other determination of a generally positive user state, and at the same time the processor determines that one or more prompts need to be delivered to the user, such as a prompt regarding recharging the chair assembly or a prompt to recommission the chair assembly, or the processor determines that the posture of the user should be adjusted by actuating one or more portions of the chair assembly, then the processor can delay the prompt or the posture adjustment until the user is no longer in the generally positive state. For example, if a user is in a flow state and the chair requires recharging, the processor might wait until the user is no longer in the flow state to notify the user or the processor might wait until the chair is at a critically low charge state to notify the user. Similarly, if a processor determines that a user is being very productive, but that their posture is not ideal to the point that the processor would like to actuate the chair assembly to adjust the user's posture, then the processor can wait until the user is no longer being very productive to adjust the user's posture. These settings can be adjusted based on user. For instance, a user can configure the processor to never interrupt a flow state, regardless of the charge state of the chair or posture of the user. A user can also program which sensed or deduces states can or cannot be interrupted. For example, a user could configure the processor to not prompt the user or adjust posture if the user's heart rate is below a certain level, if the user's stress is below a certain level, if the user's focus is high, any combination thereof, or the like.

Referring to FIG. 56, an example of a method 1700 of a processor determining whether or not to disturb a user's generally positive state is shown. The flowchart describes the method 1700 in terms of sensing a posture, determining if a user's posture requires adjustment, and then determining whether or not to disturb the user based on whether the user is in a flow state or not, but is equally applicable to any determination that a user needs to be disturbed or any generally positive state as described herein. At decision block 1702, the method 1700 includes determining if a user's posture requires adjustment. If the answer to decision block 1702 is NO, then the method 1700 repeats decision block 1702. If the answer to decision block 1702 is YES, then the method proceeds to decision block 1704. At decision block 1704, the method 1700 includes the processor determining if the user is in a flow state. If the answer to decision block 1704 is YES, then the method 1700 can return to decision block 1702. If the answer to decision block 1704 is NO, then the method 1700 can proceed to process block 1706. At process block 1706, the method 1700 can include actuating one or more aspects of the chair assembly that are expected to provoke an adjustment of the user's posture to a more ideal posture. Instead of actuating the chair assembly, the method 1700 can notify the user that the user's posture is not ideal and should be adjusted.

The chair assembly can include an on-board commissioning feature, where a user can identify preferred operational parameters for the chair by using a button, touch screen or other interface device mounted on the chair assembly itself. For example, a user can prompt the chair assembly to enter into the commissioning feature by pressing or holding a user interface, such as a button or a touch screen. An optical or audio indicator could then indicate to the user that the commissioning feature is active. The user could then set a preferred positioning of one or more aspects of the chair assembly, such as height of the seat, height of the arm rests, tension in the recline of the backrest, or the like. In another aspect, the user could set a preferred temperature for the heating function by pressing one button or location on a touch screen that raises the temperature or another button or location on a touch screen that lowers the temperature.

In another aspect, the user could set preferred heating locations. In one variation, the user could cycle through a set of pre-set heating locations by pressing a button or a location on a touch screen. In another variation, the user could activate individual heat application modules by selecting them on a touch screen. In yet another variation, if the chair assembly has a continuous heat application module, such as a smart fabric that applies heat at selective locations or a heating pad with very small heating elements, the user could activate chosen heating application locations by selecting and deselecting them on a touch screen.

In certain aspects, the chair assembly 10 can sense a changed property in the user or in the environment and can notify the user of the changed property. The notification can be a prompt for the user to utilize the commissioning feature (i.e., re-commissioning the chair assembly 10) in order to make sure the user's preferred operational parameters are set for varying user or environmental stated. For instance, if the chair assembly 10 senses that the environmental temperature is higher or lower than when the user commissioned the chair, the chair assembly could notify the user that the temperature is different and prompt the user to commission the chair at the new temperature or at least query if the user would like to re-commission the chair. For example, if the user commissions the chair during a Winter month, the chair could prompt a user to re-commission the chair on the first warm day of Spring, the first hot day of Summer, or the day that the facility changes from heating to air conditioning.

In an aspect, if the user commissions the chair when the user weighs a first weight and the user then gains or loses weight to weigh a second weight, the chair assembly 10 could notify the user that the chair was commissioned at the first weight and prompt the user to re-commission the chair for the second weight. For example, if a user commissions the chair at a weight of 200 lbs. and then loses 30 lbs. to weigh 170 pounds, the chair could prompt the user through a visual, audio, or haptic cue to re-commission the chair at the new weight. The user could then recommission the chair, indicate through a user interface that the user does not wish to recommission the chair at this time, which may cause the chair to remind the user again after some period of time, or that the user does not wish to re-commission the chair.

In some aspects, the extent of the commissioning process for a chair assembly 10 can be tailored to a particular user or category of user. The commissioning process can be more extensive for a user that is designated as a repeat user or that is anticipated to be a repeat user by selection algorithm. The commissioning process can be less extensive for a user that is designated a less frequent user or that is anticipated to be a less frequent user by a selection algorithm. For instance, in a conference facility environment, a conference room chair could have a thorough commissioning process for an employee of the conference facility, but could have a less extensive commissioning process for an attendee at a conference that is being hosted at the conference facility.

The selection algorithm could identify one or more properties of the user, such as distance a user resides from the facility, the number of times a user has accessed the facility over a certain time period, the user's job credentials, and the like, then weight those properties based on a programmed or learned set of priorities, and determine the probability that a user will be a repeat user or a less frequent user.

In another aspect, the extent of the commissioning process for a chair assembly 10 can be tailored to the intended use of the chair. For example, a chair assembly 10 that is intended for use in a single-occupant office could have a thorough commissioning process, because a single user is likely to be a repeated user of the chair assembly 10, while a chair assembly that is intended for use in a conference room could have a very brief commissioning process, because multiple users are likely to occupy the chair assembly.

As described elsewhere herein, a user's attentiveness, need for a break, productivity, flow, or combination of these can be continuously monitored. Based on this monitoring, a commissioning or re-commissioning prompt may be delivered at a time when it is determined that prompting the user is not likely to disrupt productivity. For example, if a user's flow is being monitored, and it is determined that commissioning or re-commissioning of the chair assembly 10 would be beneficial at a time when a user is in a flow state, the chair assembly 10 could wait until the user emerges from the flow state before prompting the user to commission or re-commission the chair assembly 10.

Because the chair assembly 10 in many instances is utilized to improve productivity, and because constantly interrupting a user with prompts to re-commission the chair assembly 10 would likely decrease productivity, the chair assembly 10 can have a minimum time interval between prompts to re-commission the chair assembly 10. In some aspects, this minimum time interval could be one day, two days, one week, fifteen days, three weeks, one month, or more.

The chair assembly 10 can include a feature that enables a user to prevent the acquisition of data using the sensors described herein. For example, the chair assembly 10 can include a switch labeled “PREVENT DATA ACQUISITION” in a first position and “ALLOW DATA ACQUISITION” in a second position. When the switch is in the first position, the chair assembly 10 is prevented from acquiring data from the sensors. When the switch is in the second position, the chair assembly 10 can acquire data from the sensors.

The chair assembly 10 can include a feature that enables a user to prevent transmission of data from the chair assembly 10. For example, the chair assembly 10 can include a switch labeled “PRIVACY” or “PREVENT DATA TRANSMISSION” in a first position and “SHARING” or “ALLOW DATA TRANSMISSION” in a second position. When the switch is in the first position, the chair assembly 10 is prevented from sharing data with a facility-based processor or other outside users. When data is prevented from being shared, it can still be used for on-board processing. For example, if data is not being shared, the chair assembly 10 can still measure the ambient temperature and apply heat to a user. When the switch is in the second position, the chair assembly 10 can transmit data to outside users. In some aspects, when the switch is in the first position, the chair assembly 10 is still able to share data with an individual user's devices or computers.

These switches can be in the form of a virtual switch that is activated/deactivated by a touch screen located on the chair assembly 10. These switches can be a voice-responsive switch. For example, a user can say “Chair, stop acquiring/transmitting data” to prevent data acquisition/transmission and “Chair, start acquiring/transmitting data” to resume data acquisition/transmission. In embodiments having more than a simple switch, the user can be selective about which data is acquired or transmitted. For example, using a touch screen or voice-responsive switch, a user can select to acquire or transmit data relating to occupancy, but can select to not acquire or not transmit data relating to the user's weight.

The chair assembly 10 can record a user's preferences and “learn” which settings a user prefers. For instance, if a user manually adjusts the application of heat in response to a particular ambient temperature, the processor 58 can “learn” this behavior and begin automatically adjusting the application of heat in response to the particular ambient temperature. As another example, if the chair assembly 10 and system as a whole senses that a user is repeatedly less alert after lunch, the chair assembly 10 might “learn” this and start providing additional stimuli to the user in the early afternoon.

The chair assembly 10 can include software that predicts certain settings for the user based on historical data regarding the preferences of other individuals. In some aspects, a chair assembly processor 58 can be programmed with a predictive software. The predictive software can result from an analysis of historical data. For example, the data may show that all users that are taller than six feet prefer one setting and all users that are shorter than six feet prefer a different setting. The characteristics of the user are set as variables in the historical data analysis and those variables are fit to the historically preferred settings for users. The predictive software can be updated as more data becomes available, either by user initiation or automatic updating. The predictive software can also be run remote from the chair assembly 10. In at least some cases, predictions may be used as defaults or automatic parameter settings to be used when a particular user has not already specified preferences.

In some aspects, a touch screen 1684 can be located in an armrest of an arm assembly. Referring to FIG. 57, the top surface 55 of the armrest 53 can be divided into two areas: a back portion 1686 where the elbow rests; and a front portion 1688 where the forearm rests. The back portion 1686 can be padded for a user's comfort. The front portion 1688 can be a touch screen 1684 for enhanced functionality. In some aspects, the touch screen 1684 can initially be inactive, so that the user does not accidentally perform an action on the touch screen while resting her forearms. The touch screen 1684 can then be activated by a specific user signal input to the touch screen 1684, such as a double- or triple-tap, by a voice command, such as “touch screen on”, or by other activation means. The touch screen 1684 can be configured to recognize the difference between a touch from a user's forearm and a touch from a user's hand. The touch screen 1684 can then revert to an inactive state after being unused for a certain period of time. The touch screen 1684 can display a message 1690, such as “Commissioning of chair recommended. Double-tap here to initiate commissioning sequence.” The touch screen 1684 can provide the functionality described herein with respect to a user interface. It should be appreciated that the armrest 53 and touch screen 1684 are not limited to the shapes that are illustrated.

In certain aspects, the touch screen 1684 can provide a user interface for standalone functionality of the chair assembly 10. In certain aspects, the touch screen 1684 can serve as a remote terminal for a user device. For example, if a user links their smart phone to the touch screen 1684, the user could answer calls, send text messages, and the like from the touch screen 1684 serving as a remote terminal for the smart phone. In some aspects, one or both armrests 53 can include a touch screen 1684. In some aspects, only one armrest 53 has a touch screen and both armrests 53 have the same physical dimensions and orientations, and can be swapped, so that a right-handed user can have a touch screen 1684 in the right armrest and a left-handed user can have a touch screen 1684 in the left armrest, or vice versa if so preferred.

Referring to FIG. 58, the chair assembly 10 can include wireless communicators 1692, such as a wireless transmitter, a wireless receiver, or a wireless transceiver. For applications where it is preferred that the wireless communicator 1692 be as elevated as possible, the wireless communicator 1692 can be located near the top of the back assembly 18. For applications where it is preferred that the wireless communicator 1692 not be located in proximity to a user's head when a user is in a seated position, the wireless communicator 1692 can be located within or attached to an arm assembly 20. For applications where it is preferred that the wireless communicator 1692 be located as far from a seated user as possible, the wireless communicator 1692 can be located on or in the base assembly 12, such as at a proximate end of a leg of a 5-point base (as shown), a distal end of a leg of a 5-point base (not pictured) or integrated into one of the casters (not pictured).

In certain aspects, the back assembly 18, the seat assembly 16, the armrest 53, or a combination thereof can have contact surfaces that interface with the user and that includes personalized contours that are configured to provide a continuous support surface for the user. For example, the contact surfaces can be moved by a plurality of individual actuators that move the contact surface toward or away from the user in order to provide a continuous support surface. As another example, a material that changes volume and/or shape in response to a certain electric field, magnetic field, chemical stimulus, or the like, and changes back to the initial volume and/or shape upon removal of the electric field, magnetic field, chemical stimulus, or the like, can be used to provide a user-specific contour to the contact surfaces. A processor can identify the user, then send a signal to the appropriate electric field, magnetic field, or chemical stimulus applicator directing them to apply the appropriate settings. These settings can be configured via a commissioning process. These settings can also be configured via a learning algorithm that varies the settings and monitors feedback by way of a user's flow, productivity, comfort, etc.

In some aspects, the sensing of one or more attributes of a user as described herein can be performed by a wearable device, such as a smart watch, a badge, a pin, a bracelet, a necklace, etc.

A wearable device can be utilized to sense temperature, proximity to objects including the chair assembly, heart rate, breathing rate, blood oxygen levels, stress, perspiration, movement, identity, muscle activity, alertness, emotional state, galvanic skin response, and the like. For example, a smart watch can sense a user's heart rate, blood oxygen levels, and galvanic skin response.

In some aspects, the processing functions described herein can be performed on a user's portable device or wearable device. For example, a user's portable smart phone device can receive data from one or more sensors as described herein, deduce a user's stress, flow, fatigue, need for a break, alertness, or the like, and can notify a user. Also, the user's portable device can deduce these things and can automatically cause a change in the status of one or more aspects of a chair assembly. For example, if the device deduces that the user is fatigued, the device could cause a haptic actuator in the chair to vibrate the chair in a fashion that stimulates an awakening action. As another example, if the device deduces that the user is stressed, the device may cause an olfactory actuator to release a calming aroma or could cause a heating element to apply heat to a portion of the user's body that is medically known to reduce stress. If the device deduces that the user needs a break, the device could alert the user and recommend that the user take a break.

In some aspects, the control of data related to the chair assembly 10 might be user controllable through a software application on a personal device. In this way, a user can either opt out or opt in to sharing certain kinds of data. A user's data privacy settings can follow the user from one chair assembly 10 to another chair assembly 10, without requiring additional opt in or out selections. For example, referring to FIG. 59, an app 1712 shown on a user's device screen 1714 could have multiple privacy settings for certain kinds of data. As an example, referring to FIG. 54, the app 1712 has three privacy settings, a “Do Not Share” setting 1716 for the right column which indicates data that will not be shared, a “Share w/ Facility” setting 1718 for the middle column which indicates data that will be shared with the facility, but not with the manufacturer, and a “Share w/ Facility & Manufacturer” setting 1720 for the left column which indicates data that will be shared with the facility and the manufacturer. In the example shown in FIG. 59, the user has selected to share maintenance data, power management data, and chair alignment data with the facility and manufacturer, has selected to share temperature data, user flow data, user posture data, and occupancy data with the facility, and has selected not to share user weight data. In certain applications, a facility administrator can override the user's preferences for one or more kinds of data. In certain applications, when a facility administrator can override a user's preferences, the user can still have the ability to opt out of data sharing entirely. In some aspects, data shared with the manufacturer or the facility can be anonymous. In some aspects, anonymity is a user preference set within the app 1712. Other options for entities to share data with include, but are not limited to, a health care provider, a health insurance provider, a health rewards service, an individual of the user's choosing, such as a spouse, an educational institution, a governmental agency, a non-governmental organization, scientific research organizations, a social media site, and the like.

The chair assembly 10 can provide data for a user that can be compared with other users in a facility, a workgroup, a company, or any other group of users. Researchers have discovered that reporting energy usage of a person's neighbors can have positive impacts on a person's energy efficiency performance. A similar concept can be applied with the data acquired from the chair assembly 10 described herein. For example, if a user's flow is sensed by the chair assembly, the chair assembly 10 can provide a report at daily, weekly, or monthly intervals, or any other time interval comparing the amount of time a user spends achieving flow to others within a group. After receiving a report, a user might be more motivated to take active steps toward increasing the amount of time during the workday that is spent achieving flow. Similarly, if a user that typically sits with poor posture receives a report indicating that the average person in their work environment spends a large percentage of time sitting with excellent posture, it might motivate the user to strive to sit with better posture. By generating and delivering these reports to users, a facility or company might be able to prompt an improvement in work performance.

In still other cases, a system may present posture, flow or other progress reports to a user to show how that user's characteristics change over time. For instance, where a user initially pas poor posture but continually makes changes that lead to better posture over time, the progression from poor toward excellent posture may be reported to the user periodically. Similarly, a regression in sensed posture may be indicated to a user. Increases and decreases in flow efficiency over time may also be reported to a chair user. Other health trends that may be periodically reported include hear rate, temperature, weight, alertness, fidgetiness, degree of movement, etc.

As described above, chair assembly 10 can go through a re-commissioning procedure when the chair assembly 10 senses that one or more ambient properties is change relative to the ambient property during the initial commissioning procedure. The re-commissioning prompt can be delivered via a wearable device, such as a smart watch or a earpiece. The re-commissioning prompt can be delivered via a portable device, such as a smart phone, a tablet, or the like. In addition, the determination regarding the need for re-commissioning can also be made on the device. For example, the device can receive data relating to the environmental or user conditions, can process the data through a decision-making algorithm, and can make recommendations for re-commissioning when certain conditions are met.

A device can utilize the chair assembly 10 in concert with other affordances in a space to alter a user's condition or integrated experience. For example, if the system determines that a user is not currently in a flow state, the system can prompt the alteration of the lighting, sound, temperature, and other aspects of the environment using other affordances, while actuating the positioning of the chair assembly 10, actuating the temperature of the chair assembly 10, or any other actuating of the chair assembly 10 that is known to promote a flow state. Similarly, the device can alter the environment using other affordances and can alter the chair assembly 10 to promote reduced stress, increased productivity, increased focus, increased social behavior, improved collaboration, more or less user movement, and the like.

As described elsewhere herein, the chair assembly 10 can perform functions based on data received from remote sensors. Remote sensors can include, but are not limited to, a camera, a wearable device, a swallowed sensor, an injected sensor, an implanted sensor, or the like.

Referring to FIG. 8, a camera 100, 102 can monitor certain aspects of a user seated in a chair assembly 10. A camera can be used to monitor a user's posture by acquiring images and processing the images via a posture-assessment algorithm known to those having ordinary skill in the art. A camera can also be used to monitor a user's breathing rate by monitoring the motion within a user's chest cavity or abdomen. A camera can further be used to monitor a user's movement by monitoring the motion of all parts of a user's body. A camera can be used to monitor a user's heart rate by monitoring the slight movement of the skin near the jugular vein, by monitoring slight variations in retinal reflections, or the like. A camera can be used to monitor a user's facial expressions using facial expression recognition software known to those having ordinary skill in the art. A camera can be used to monitor a user's eye movement by using eye movement tracking algorithms known to those having ordinary skill in the art. A thermal camera can be used to monitor a user's surface temperature. A camera can identify a user using facial recognition technology. A camera can identify a user that is wearing a non-visible emitter, such as an infrared emitter, by acquiring an image that is sensitive to the non-visible emission from the non-visible emitter.

As described above, for certain types of sensors, the sensing capability is particularly good where a sensor surface makes direct contact with some part of an employee's body. For this reason, certain parts of a table top or work surface are particularly advantageous for supporting sensor devices. Referring again to FIG. 31, table top sensor devices 512 should be located immediately adjacent or even within an edge portion of a table top so that an employees wrists can rest thereon and make direct contact therewith during keyboard operation. As shown, in at least some particularly useful embodiments, two direct touch sensors are provided in the top surface of table assembly 32 where a small gap exists between the two sensors. Each of the separate table top mounted sensors should be capable of independently sensing a user's physiological parameters (e.g., heat rate, temperature, etc.). Referring still to FIG. 31, in some cases the table associated sensors have a length dimension between three inches and ten inches each to accommodate different users that may position their hands/wrists differently during keyboard operation. Each sensor 512 in the table top should be within one quarter to two inches of an adjacent table edge and should have a width dimension between one inch and four inches to accommodate different positions of user wrists on the table top surface.

In at least some cases top surfaces of the sensors 512 in the table top may be substantially flush with the top surface of the table assembly 32. In other cases the sensors may stand proud of the table top so that they offer elevated wrist support to a station user. In still other cases the table associated sensors 512 in FIG. 31 may comprise wrist support structure independent of the table top.

Keyboard 510 in FIG. 31 also includes a pair of direct touch sensor devices 512 that may have characteristics similar to the characteristics of the table top associated sensors described above. Thus, each keyboard sensor has a length dimension to accommodate different wrist locations and may either be substantially flush with adjacent board surfaces or may stand proud to offer additional wrist support.

A system camera may also be integrated into other space affordances. For instance, in some cases a system camera or other type of sensor device may be integrated into a desk lamp or other lamp structure. To this end, see the exemplary lamp structure 1898 shown in FIG. 60 that includes a base 1900, a support arm 1902 and a light head member 1904 where a camera is mounted within the head structure at 1906. Here, the camera 1910 may be mounted to swivel about the head structure so that the camera can be optimally placed at a location in front of a user with the user's head or torso generally located in the field of view of the camera.

In still other cases, a system camera may be mounted to a monitor support arm structure, to a credenza, a shelf member or a partition wall or architectural wall structure immediately in front of a location at which a user typically works. In at least some cases a camera device including a wireless transceiver may be retrofittable to a system including a chair and other components so that a user can position the camera at any optimal location relative to the user.

In still other cases a user may be able to sync her smart phone which includes a camera to her system so that a smart phone camera can obtain images useable by a system processor to perform many of the parameter analyzing steps. In this case, a smart phone camera could obtain useful images of the user and a display screen on the same smart phone device could present feedback to the user. For instance, the phone camera images may be used to determine a user's heart rate and that rate may be reported back to the user via the phone screen as well as being used for some other purpose (e.g., an overall wellness assessment of the user and to provide posture or other suggestions, to control chair actuators to change posture automatically, etc.).

A swallowed sensor can be used to monitor a user's core temperature. The core temperature data can then be used by the chair assembly 10 to actuate heating or cooling elements, as described herein. The swallowed sensor can communicate wirelessly with a processor that utilizes the data acquired by the swallowed sensor in one or more of the ways described herein.

An implanted sensor can be used to monitor a user's core temperature, surface temperature, heart rate, breathing rate, brain activity, muscle activity, blood oxygenation, blood sugar levels, and the like. In some aspects, the implanted sensor can be powered by a user's blood stream. In some aspect, the implanted sensor can be powered by a battery that is recharged using wireless recharging. In some aspects, the implanted sensor can be powered by a communication signal.

Data gathered from sensors in the chair assembly, from a wearable device, from a user's portable device, or from the remote sensors described herein, can be collectively used by a processor to derive a property or state of a user that cannot be directly measured or is more efficient to derive than to directly measure. For instance, given a sufficient number of inputs, a user's flow state can be derived.

If multiple users are using multiple chair assemblies 10 as described herein, a processor can receive data from the multiple chair assemblies 10 and make a determination as to the state of collaboration of the users. For example, the processor can receive proximity and orientation data from sensors within a set of chair assemblies 10 or a remote sensor that is sensing the set of chair assemblies, and if the chair assemblies 10 are within a certain distance of one another and generally facing one another, then the processor could begin assessing the state of collaboration. For example, if the processor receives data indicating that a single person is dominating the conversation in a collaborative environment, then the processor might score the interaction at a low level of collaboration. If the processor receives data indicating that the conversation is moving freely about the group in the collaborative environment, then the processor might score the interaction at a high level of collaboration. As another example, the processor could receive data relating to how the users in the collaborative environment are seated relative to one another and determine the state of collaboration as a result. This collaborative assessment can be based on the best available scientific knowledge relating to the study of collaborative working environments.

The chair assembly 10 can be an integrated part of a network of smart devices. In such a network, the chair assembly 10 can serve as a storage point for a user's individual preferences for the chair assembly 10, as well as the user's individual preferences for the other smart devices. In the alternative, a user's preferences may be stored in a remote system database so that the preferences can be accessed and used to customize automatic control of any chair used by a specific user that has controllable features. Thus, for instance, where an employee works in many different enterprise facilities and therefore uses many different chairs, each controllable chair can be controlled in a fashion that best meets the user's preferences.

In at least some cases it is contemplated that a smart phone or other portable computing device that includes a processor and wireless communication capabilities may provide most if not all of the processing power required to operate a smart chair assembly including sensors, actuators and other components. While many different types of portable devices may be used to drive a smart chair assembly, an exemplary smart phone device will be described in the following example. Here, a smart chair assembly may include several sensors and actuators as described above for sensing a user's physiological parameters and for adjusting chair assembly components to meet user preferences, encourage healthy use of the chair assembly, or to encourage any other type of activity. The chair assembly would also include a transceiver (se 1692 in FIG. 58) for wirelessly communicating with a smart phone device. In the present example it will be assumed that a chair assembly application can be downloaded to a smart phone where the application is designed to work with the chair assembly to perform various tasks and functions.

In order to interact with a chair assembly, a smart phone and the smart phone application have to be associated with the chair in some way. One particularly useful way to associated a smart phone with a specific chair assembly is to use the phone to identify the specific chair assembly and associate with the identified chair assembly automatically. For instance, most smart phones include a camera that can be used to take an image of a bar code, dot matrix code, QR code, or some other type of code (hereinafter a “chair code”). In these cases, a chair code that uniquely identifies a specific chair assembly may be attached to a chair and the camera may be used to take an image of the chair code which can then be used to identify the specific chair. In at least some cases it is contemplated that a remote database may stored chair codes associated with specific virtual addresses so that each specific chair code corresponds to a specific virtual address that can be used to communicate with the chair assembly.

In at least some cases it is contemplated that obtaining an image of a chair code on a chair may cause a smart phone to automatically download and access a chair control application so that the chair user does not have to download the application in a separate step. In other cases, the chair user may have to first download the chair control application and then obtain an image of the chair code from within the application to associate the phone with the specific smart chair assembly.

In other cases where a smart phone includes a near field RF or other ID reader, an RF or other type of identification tag may be attached to the smart chair and that tag may be read periodically to associate the chair and the smart phone. For instance, here, the association may be made automatically when the smart phone is initially proximate the chair and may be reconfirmed every few seconds. Here, when any system sensor (e.g., a pressure sensor, a camera, etc.) senses that the user has left the chair (e.g., a user stands up), the association may be discontinued or the action may cause the smart phone to attempt to re-associate with the chair.

Once a smart phone is associated with a specific smart chair assembly, in at least some embodiments the chair assembly can simply be used by the user and various processes may commence automatically. For instance, as a user adjusts the chair actuators, the adjustments may be transmitted to the smart phone to be memorialized. As sensors in the chair sense different postures and other physiological parameters, the sensed parameter values may be transmitted to the phone for archiving or other processing. When an unhealthy posture or some other condition that is not optimal is sensed, the smart phone can provide messages to the chair user via a display on the smart phone device to encourage better posture or some other action to optimize parameters. Where actuators in the chair can be automatically controlled, the smart phone may present control signals thereto to automatically adjust parameters in an attempt to achieve some positive goal (e.g., better posture, relieve perceived or indicated pain, cause healthy repositioning of the chair user periodically, etc.).

In cases where chairs are assigned to single users or are routinely used by single users over at least some period, the smart phone application can be used to at least semi-automatically re-associate with the assigned chair each time the user uses the chair. For instance, after a smart phone is associated with a specific chair, if the user leaves the chair at the end of a day and then comes back to that chair the next day, when the user sits in the chair and a pressure sensor in the chair recognizes that someone is occupying the chair, a chair processor may broadcast a signal including a chair identifier which is received by the smart phone application. Here, the smart phone application may recognize that some user is occupying the chair and may request that the user obtain another image of the chair code to re-associate the phone with the chair.

In other cases when the user sits in a chair, sensed user parameters may be used to at least partially identify the user and then to associate the chair and the specific user's smart phone. For instance, in a simple case, once a user uses a chair and the chair is associated with the user's smart phone a first time, the user's weight as sensed by the chair may be stored for re-association. The next time the user sits in the chair, the chair may sense user weight and use that as a simple identifier to identify the user and attempt to associate the chair with the user's smart phone application to enable smart phone control of the chair.

In still other cases where a location tracking system is capable of locating user smart phones and other portable devices as well as smart chairs and other affordances in an enterprise space, the locations of user smart phones and chair assemblies may be used to associate and then re-associate smart phones and chairs. For instance, in at least some cases when a user's smart phone is not already associated with a specific chair assembly, the smart phone application may be programmed to routinely query for smart chair assemblies in a small area (e.g., an 8 foot radius). When a smart chair assembly is identified and the chair assembly generates a signal indicating that a user occupies the chair (e.g., a pressure sensor identifies that a user sat down), specific locations of the chair assembly and the user's smart phone device may be determined and, if the chair and smart phone locations are within some predefined threshold distance of each other, the application may automatically associate the phone with the chair. Here, re-association would be performed in substantially the same manner.

In some cases the smart phone may either provide a commissioning option to the user or may automatically initiate a commissioning option the first time the phone is associated with the smart chair or any smart chair. In some cases the commissioning process may be extremely simple such as, for instance, having the user set preferred chair settings (e.g., temperature, height, seat depth, lumbar support, force required for backrest to recline, etc.) to preferred settings and then storing the settings so that the settings can be subsequently used to automatically set parameters for the user in the future. In other cases more complex commissioning processes are contemplated.

In some cases a commissioning procedure may cause a smart chair assembly to cycle through different parameter settings and may request feedback from a user for at least a subset of the parameter settings. For instance, regarding heat settings, where a chair assembly includes several heat elements that can be independently controlled to apply heat to different locations on a seat and/or a backrest assembly, the heat elements may first be controlled to cycle through different heat patterns, holding each pattern for 20 minutes unless a user affirmatively indicates a desire to move on to a next pattern. At the end of each 20 minute period, a system processor (e.g. in a smart phone, a remote server, etc.) may query the user to determine if the user liked or disliked the heat pattern. After all heat patterns have been tested, the system processor may store the preferred pattern or the top N preferred patterns for subsequent use with the user. Continuing, the system may cycle through different heat levels using the preferred heat pattern(s) continuing to gather user preference information. Other chair parameter options may be automatically cycled through to obtain user preferences for subsequent use.

It has been recognized that different people have very different body types and body characteristics. For instance, some people are very thin while others are very heavy, some people are tall while others are short, some people have relatively wide shoulders while others have a slimmer build, etc. Because people's bodies have different characteristics, their bodies typically be perceived very differently by chair sensors. For instance, a tall, heavy and wide person with good posture in a chair may be perceived very differently by a processor considering chair pressure sensor signals than would a thin, light and narrow person that is also sitting with good posture. In fact, if the signals associated with the tall, heavy and wide person's good posture were to be considered optimal, the sensed signals for the other person in this example likely would result in a determination that the other person's good posture is actually poor.

As another instance, a first person with good posture may naturally lean back against a backrest support structure with a first force while a second person with good posture may naturally lean back against a backrest support structure with a second force that is substantially different than the first force. Here, if good posture is associated only with the first force level, then the second force level applied by the second user would be erroneously associated with bad posture.

For this reason, in at least some cases it is contemplated that various user parameters may be determined during a commissioning process which would then be used subsequently for the specific user associated therewith to recognize good posture and poor posture as well as other physiological positions the user may assume and then to coach that user on good posture and other parameters.

It has also been recognized that in most cases, even if a person generally has poor posture, that person can often assume a good posture position for at least a short period by sitting upright with two feet on the ground, moving her buttocks rearward on a seat, rolling shoulders back, and holding head high. During a commissioning procedure, a chair user may be instructed via a smart phone (or other device) to assume a good posture in a smart chair assembly. Here, the application may coach the user on what a good posture position is (e.g., feet on ground, head up, shoulders back, etc.). Once the user assumes a healthy or good posture, the user may select an on screen icon or otherwise indicate that the user is in a good posture position. Next, the application may cause the chair pressure sensors or other sensors to detect sensor signal values associated with good posture for the specific user and that information may be stored in a database for subsequent use. Here, where a chair includes 10 pressure sensors or sensor devices that can sense pressure in 10 different locations, the combination of sensor signals for the specific person may be stored as a “good posture sensor signature” for the specific user. Thereafter the sensor signature may be used as a target or goal for comparing user postures to assess when good posture occurs and when other postures occur.

In at least some cases a smart chair may be able to help a user achieve certain health goals over time. For instance, where a user would like to improve her posture, the smart chair may be controlled to help the user improve posture over time. Here, in as least some cases, it is contemplated that during a commissioning procedure, a good posture sensor signature for an employee may be obtained as described above and used as a good posture target or goal. Subsequently, during chair use, the smart phone application or an application run by another system processor may be programmed to monitor user posture for some time such as, for instance, two days of use, a first week of use, etc., to develop a baseline or a current state of user posture.

After a current posture baseline is established, the smart phone application may start to encourage posture changes in a series of steps designed to, ultimately, lead to a better posture and, in some cases, the target or goal posture identified during the commissioning procedure. For instance, a first step may be to encourage the user to maintain her feet flat on the ground so that the bottom of her thighs are typically sensed at the front edge of the chair assembly seat. A second step may be to encourage the user to move her buttocks rearward on the assembly seat. A third step may be to encourage the user to roll her shoulders back so that her shoulder blades are sensed by sensors in the upper lateral portions of a backrest and so on. Here, one step may need to be routinely met prior to starting to encourage the next until good or at least better posture results. Here, as in the case of other embodiments described above, encouragement may be via simple messages to the chair user via the smart phone application. In other cases the chair actuators may be controlled in some fashion to encourage posture correcting steps such as applying heat, vibrations, etc., at different locations that the user will want to experience thereby causing the user to assume a better position where the heat, vibration, etc., is directly experienced. In still other cases, actuators may be automatically controlled to cause good behavior in some fashion (e.g., move seat backward or forward to change posture, move lumbar support in or out, etc.).

In at least some cases, in addition to establishing a good posture signature for an employee during a commissioning procedure, other posture signatures may be established for various purposes. For instance, during a commissioning procedure, a user may be instructed to assume a “normal” posture that the user would typically assume when sitting in a smart chair. Here, the chair sensors would sense signals indicative of the normal posture and store that set of signals as a normal posture or initial signature. The initial signature could then be used as a baseline for comparison to the good posture signature to automatically develop a plan to correct the user's posture over time. This process of establishing initial posture issues and a target posture (e.g., the good posture signature) is akin to an orthodontist working with a person to correct alignment of teeth over time, starting with a patient's teeth as they initially are and moving toward an ultimate goal of good or at least better alignment for a specific patient. In the case of the smart chair, the commissioning process enables an understanding of posture issues and a target and would help formulate a plan for how to correct posture issues.

Other posture signatures developed during commissioning may include a “perched signature” where the user is instructed to sit on the front edge of a chair seat while a sensor signal set is generated and stored, a “left leg crossed” signature where the user is instructed to cross her left leg over right while a sensor signal set is generated and stored, a “right leg crossed” signature where the user is instructed to cross her right leg over left while a sensor signal set is generated and stored, etc. Once multiple position signatures are obtained and stored, the application or system should be able to very clearly distinguish one posture from others.

As indicated above, in general a person should not sit in the exact same position for long periods of time. For this reason, in at least some cases, the smart phone application may encourage different relatively healthy positions every few minutes. For instance, an application may encourage a user to cycle through the good posture, left over right leg posture, right over left leg posture and perched posture every 30 minutes so that the user moves periodically. Here, where the user is already moving periodically or even more than an application prescribes, sensing of those movements may cause the application to skip presenting messages to encourage additional movement.

In at least some cases it is contemplated that an application may take into account information in addition to an initial posture and a good posture signature to develop a corrective posture plan. For instance, during a commissioning procedure a user may be queried about back, wrist, leg or other pain that occurs persistently or sporadically while using a smart chair. Answers about experienced pain may be used to form a pain signature for the specific user. In at least some cases an application may use each of an initial posture signature, a good posture signature and a pain signature to develop a plan for achieving better posture.

In at least some cases a user will be queried about pain subsequent to an initial commissioning procedure so that the application can track the effects of corrective messaging or actuator control and, in at least some cases, to adjust a better posture plan accordingly. For instance, at the end of each day of use, a simple query may be presented to a chair user requesting information about experienced pain. Where pain persists or is exacerbated, a better posture plan may be modified. Where pain is alleviated or eliminated, the initial plan may be continued.

In at least some cases it is contemplated that the application may also at least periodically analyze better posture plan results and present that information to a chair user automatically. For instance, if a user's posture improves and moves from the initial posture signature toward the good posture signature for the specific user, that information will be reflected in a different posture signature sensed by the chair sensors which can be used to indicate better posture textually or even graphically to the chair user via a smart phone display screen or other display screen used by the chair user. Similarly, as pain subsides and is reported by the user to the application over time, that development can be reported back to the user along with an updated posture signature to show posture corrective progress as well as to encourage further efforts on the part of the user to achieve the ultimate good posture signature.

Where a smart phone application controls a smart chair assembly, the smart phone application may also be useable to control other devices or affordances proximate a smart chair in conjunction with the smart chair in some cases. For instance, a light device, speakers, a camera, a heating device, that are independent of the chair assembly may be controlled along with the chair assembly to control a chair user's environment in different ways. Here, in at least some cases it is contemplated that each other device or affordance that may be controlled by a phone application may includes its own processor and transceiver for receiving control commands from the phone application. Here, in at least some cases, when a user initially associates a chair with a smart phone, separate steps may also be performed to associate the phone with other affordances in space including a light, speakers, a camera, etc.

In at least some cases it is contemplated that a phone application may be associated with other affordances in the same way that a smart chair is associated with the application. For instance, after obtaining an image of a chair code from a smart chair, images of similar codes on other affordances or resources may be obtained while in the smart phone control application. Each resource code may then be used to identify a virtual wireless address for an associated light, camera, etc., and a small network of devices may be formed, a sort of local internet of things (hereinafter a “local IOT”), to be controlled by the smart phone application. Here, for instance, if the smart phone application receives signals from the chair assembly or a networked camera that indicate that a chair user is losing focus, the application may cause a vibrator in the chair it vibrate and stimulate the chair user and at the same time increase intensity of light generated by a networked light device.

In at least some cases it is contemplated that resources may be added to or removed from a local IOT and the application will automatically change its operation as a function thereof. For instance, a user may only have a chair initially and a stimuli would, in that case, only be provided via the chair assembly. Thereafter, the user may take steps to associated a coded light device with the application and thereafter the application may provide stimuli via both the chair and the light device.

Consistent with the above aspects, see FIG. 61 that includes a chair assembly 10, a light device 2002, speakers 2004 and a high definition camera 2006 as well as a smart phone assembly 2008 to be used with the other components. Each of the chair assembly 10, light device 2002, speakers 2004 and camera 2006 includes a resource tag or code 2010, 2012, 2014 and 2016 that can be read or imaged via the smart phone camera to associate the phone and the affordances. Again, during a commissioning procedure, a user can obtain an image of code 2012 via the phone assembly 2008 causing the phone assembly to download and open up an affordance control application. The application may instruct the user to obtain images of other resource codes 2012, 2014 and 2016 to associate those resources with the application and the specific chair 10 to be used by the user. Thereafter, either a commissioning procedure may commence or the application may automatically start controlling affordances in the local IOT according to any of the processes and methods described above. Subsequently, if the user wants to add another resource or device to the network for control purposes, the user can simply reaccess the application and obtain another image of a resource code causing the application to automatically change the control program to accommodate the added resource and take advantage of resource characteristics.

In still other cases a local IOT may be formed that is controlled by a local or system related computer or server without requiring a personal portable device after initial commissioning. For instance, referring again to FIG. 61 and also once again to FIG. 7, after a local IOT is created using smart phone 2008, the local IOT may be associated with a facility based processor 54 for control purposes. Here, processor 54 would receive signals via access points 69 or other receiver devices from chair sensors or other system sensors and would control the chair assembly and other resources associated with the local IOT as a function thereof. In still other cases, after resources are added to a local IOT, control thereof may be passes on to the chair assembly processor 58 shown in FIG. 7 so that the smart phone or other device is either out of the loop or only operates as a sensor or an output device.

Where a chair is routinely used by more than one user, preferences, posture profiles, local IOTs, and other user specific parameters for each user would be established during a commissioning procedure in at least some cases and would be used to facilitate user specific control. Thus, where a first user specifies a first local IOT and a second user specifies a second local IOT for a specific chair and proximate resources, a system processor (e.g., smart phone or facility based) would change the IOT as a function of the user specific local IOT.

In cases where a first user uses different chairs and proximate resources at different times (e.g., in the case of a user that “hotels” in different facility spaces at different times), user specific preferences, posture and pain signatures, local IOTs and other parameters may be automatically applied to different chair assemblies and proximate affordances in at least some embodiments. For instance, if a first user initially uses a first chair and proximate light device and camera for a three hour period and then moves to a different location and a second chair and proximate second light and second camera, the same parameters used to control the first chair, light device and camera may be used to control the second chair, light device and camera.

Association with the first chair and proximate affordances and then with the second chair and proximate affordances may be made in any of several different ways. For example, if a first user is the only person in an enterprise space (e.g., in an office or a conference room), when chair sensors for a specific chair generate signals indicating that someone sat in that chair, a system server or processor may be programmed to assume that the first user (e.g., the only person in the space) is the person that sat down and preferences and other parameters for that specific user may be applied. As another example, if first, second and third employees are located in a specific enterprise space and the first and second employees are already associated with first and second smart chair assemblies and associated proximate resource sets, if a third smart chair assembly generates sensor signals indicating that someone sat down in the chair, a system processor or server may be programmed to associate the third employee and her preferences and other parameters with the third smart chair and proximate resources and to therefore apply those parameters to controlling the chair and associated resources. As still one other example, cameras and other tracking system devices (e.g., triangulating access points, proximity sensors, etc.) may be used to track specific user locations and automatically associate specific users and their associated preferences and other parameters with specific chair assemblies.

In at least some embodiments a system server or processor may first attempt to associate a smart chair and other proximate resources with a specific user and user's parameter set (e.g., preferences, posture and pain signatures, an IOT signature, etc.). In some of these cases, the server may resort to querying a user for confirmation of association only when association cannot be automatically established beyond some threshold level of confidence (e.g., 90 to 100% confidence level that association is correct). For instance if the system server can only establish association with a 50% confidence level that the association is intended, the server may query a user via a smart phone display screen or other display screen in the vicinity of the user to confirm which chair and other resources the user is using.

In at least some cases it is contemplated that upon association of a user's parameter set with a smart chair and/or other resources, some aspect of the chair or other resource may be controlled according to some convention that can be learned and known by all users as a confirmation of association. For instance, when a first user approaches a smart chair assembly and sits down in the chair, if a server or processor automatically associates the user's preference set with the chair, a vibrator device in the chair assembly may be automatically controlled to vibrate three times in rapid succession to confirm automatic association. In another case where a chair assembly includes a light device (e.g., an LED built into a lower surface of a support arm rest member), the light device may be pulsed on and off in rapid succession three times to generate an automatic association confirmation signal for the user to perceive. In still other cases a small speaker or other sound generating device on a chair may generate a sequence of three beeps or other sounds to indicate automatic association.

Other devices that are automatically included in a user's local IOT may generate perceivable automatic association signals as well including a light device (see again 2002 in FIG. 61) which may flicker on and off or flicker to increase and decrease light intensity three times to indicate automatic association, speakers (see again 2004 in FIG. 61) that may generate a sequence of three beeping sounds or a camera (see 2006 in FIG. 61) that may include a built ing LED 2020 or sound generating device 2022 to generate a three part visual or audio signal to indicate automatic association.

In particularly advantageous embodiments the signals used to indicate automatic association of different resources will be similar in all cases. For example, in some cases each associated device will generate a sequence of three beeps to indicate automatic association. In some cases the association signals generated by a set of devices in a local IOT will be controlled to automatically stagger the association signals so that a chair user can clearly distinguish one from the others. For instance, in the case of FIG. 61, chair assembly 10 may generate a first sequence of three beeps followed by light device 2002, followed by speakers 2004 and finally followed by camera 2006.

Above we describe how different people have different body characteristics and therefore that it is important in at least some embodiments to customize how a system server or processor perceives sensor signatures to specific smart chair assembly users. Thus, good posture for a first user may have a sensor signature that is substantially different than a good posture signature for a second user. Similarly, other conclusions that should be drawn from sensed parameter sets may be highly user specific. For instance, “flow” may be sensed differently for different chair and other resource users.

It has also been recognized that flow and perhaps other conclusions about user conditions may not be easy to simulate during a temporally defined commissioning procedure. Thus, where a commissioning procedure takes 15 minutes to complete, in most cases it will be difficult for a user to enter a flow state in that 15 minute period and hence allow a system to determine a flow signature of sensor values for that user.

To enable capture of a flow signature for a specific user, in at least some embodiments it is contemplated that the system will enable a user to indicate a flow state at any time. Here, for instance, if, while using a smart chair and other proximate resources, a user recognizes that she has been in a flow state for the last 30 minutes, the user may be able to indicate her perceived recent state in some fashion. When the perceived state is indicated, a system server may be programmed to look historically at sensed parameters over some previous period (e.g., the most recent 20 minutes) to establish a flow signature for the specific employee. The flow signature may then be stored for subsequent use in determining when the specific user is in a flow state.

Other state signatures may also be established for a system user including, for instance, an agitated state, a relaxed state, etc. Here, the system may enable a user to indicate any of several different states that the user perceives which would then be associated with sensor value sets obtained during a previous period (e.g., again a previous 20 minute period).

The disclosure describes particular embodiments, but one of skill in the art will appreciate that various modifications can be made without departing from the spirit of the disclosure. Thus, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the following appended claims. For example, although the system is described above for use as furniture in an office environment, in some applications, the furniture can be used in medical applications, such as, for example, a table carrying surgical tools, a bed sensing and altering patient characteristics, and the like, or in a home environment, such as a sofa, a bed, a table, and the like. The furniture can also be used in waiting rooms, cafeterias, show rooms, classrooms, and various other locations.
